ASME 61.15-1995
UNIFIED INCH SCREW THREADS (UNJ THREAD FORM)
SECTION 1 GENERAL
(E) 1.1 Scope
This Standard establishes' the basic triangular pro- file for the UNJ thread form, provides a system of designations, lists the standard series of diameter- pitch combinations for diameters from 0.060 to 6.000 in., and specifies limiting dimensions and tolerances.
It specifies the characteristics of the UNJ inch series of threads having 0.1501 1P to 0.18042P designed ra- dius at the root of the external thread, and also having the minor diameter of the external and internal threads increased above the ASME B1.1 UN and UNR thread forms to accommodate the external thread maximum root radius.
1.2 Field of Application
The UNJ screw thread is designed for aerospace inch threaded parts, or for use on other highly stressed applications requiring high fatigue strength. For aero- space applications, only Classes 3A and 3B should be used.
1.3 Assembly
Threads conforming to the UN profile (ASME B1.1) and the UNJ profile are not interchangeable because of possible interference between the UNJ external thread minor diameter and the UN internal thread minor diameter. However, the UNJ internal thread will assemble with the UN external thread.
1.4 Federal Government Use
When this Standard is approved by the Department of Defense and federal agencies and is incorporated into FED-STD-H28/4, Screw Thread Standards for Federal Services, Section 4, the use of this Standard by the federal government is subject to all the re- quirements and limitations of FED-STD-H28/4.

UNIFIED INCH SCREW THREADS (UNJ THREAD FORM)
SECTION 4 THREAD CHARACTERISTICS
4.1 Length of Thread Engagement, LE
Tolerances specified in Table 5 are based on a length of engagement equal to the basic major diameter for the UNJC, UNJF, and 8-UNJ series and are appli- cable for lengths of engagement up to 1.5 diameters; and a length of engagement of 9 pitches for the UN- JEF, IZUNJ, and 16-UNJ series, and are applicable for lengths of engagement of 5 to 15 pitches.
For lengths of engagement over 1.5 (to and in- cluding 3 diameters) or over 15 (to and including 30 pitches), the pitch diameter tolerances are 1.25 times the tabulated values. For lengths of engagement over 3 diameters or 30 pitches, the pitch diameter toler- ances are 1.5 times the tabulated values.
In addition to increasing pitch diameter tolerances for long lengths of engagement, maximum-material gages (GO) used for acceptance shall be equal in length to the design length of engagement.
4.2 Tolerance System
The system of tolerances and allowances is based on ASME B1.1 inch screw thread system of tolerance classes. Tolerances and allowances are applied plus for internal threads and minus for external threads.
4.3 Limits of Size
The basic profile dimensions are given in Table 1. The profile dimensions and tolerances shown in Figs. 2 and 3 and their values for the standard series are specified in Table 5 . For special threads for which there are no tabulated values, use the formulas in paras. 4.3.1 through 4.3.4, together with the tolerance table in Appendix B. Constants for the special thread formulas are given in Table 3.
NOTE: The dimensions and tolerances listed in Table 5 have been calculated and rounded to the procedures specified in ASME B1.30. As a consequence, a few of the values listed vary from 0.0001 in. to 0.0002 in. from listed values in previously issued standards for UN and UNJ inch threads.

4.4 Thread Form Tolerances
4.4.1 Cumulative form variation is the combined effect on functional size due to individual thread form variations in lead (pitch), helix, flank angle, taper, and roundness.
When measurement is specified for Classes 3A and 3B threads, cumulative form tolerance shall be 0.5 times pitch diameter tolerance. If not specified, con- trol shall be by the required system gages.
4.4.2 Lead and Flank Angle Variations (a) When individual inspection of lead (including
helix) and flank angle variations are required, the allowable variations for these characteristics shall be in accordance with Tables 6 and 7 unless otherwise specified.
(b) For sizes not included in Tables 6 and 7, the allowable lead variation is equal to 0.57735 times one- half the pitch diameter tolerance. This is the lead variation which causes a change in functional diam- eter equal to 0.5 times the pitch diameter tolerance. The allowable flank half-angle variation in minutes of arc is equal to 30 plus 1.875 times the number of threads per inch rounded to the nearest 5 minutes for 32 threads per inch and coarser, and 62 plus 0.775 times the number of threads per inch rounded tQ the nearest 5 minutes for threads finer than 32 threads per inch.
EXAMPLE: 0.945-8.5 UNJS-3A; lead and angle control required. No lead and angle tolerances were specified nor do default values
appear in Tables 6 and 7. Values are calculated as follows: Lead tolerance= 0.57735 X 0.5 Td2 Pitch diameter tolerance Td2 = 0.0050 Lead tolerance=0.57735 X 0.5 xO.OO50=0.0014 in. Angle tolerance (for coarser than 32 tpi) = 30 + (1.875 x tpi) Angle tolerance= 30+ (1.875 x 8.5)
= 45.94 minutes = 45 minutes when rounded to nearest 5 minutes
EXAMPLE: (El 0.500-41 UNJSJB; lead and angle control required. Lead tolerance = 0.57735 x 0.5 Tdz Pitch diameter tolerance Td2 = 0.0031 Lead tolerance = 0.57735 X 0.5 X 0.0031 = 0.0009 in. Angle tolerance (for finer than 32 tpi) = 62 + (0.775 x tpi) Angle tolerance = 62 + (0.775 x 41)
= 93.78 minutes = 1 degree and 35 minutes when rounded to near-
est 5 minutes
(C) If lead and angle tolerances are specified as a pitch diameter equivalent in terms of pitch diameter tolerance, tolerances in accordance with para. 4.4.2(a) or para. 4.4.2(b) may be adjusted proportionately using 0.5 times pitch diameter tolerance as a basis.

UNIFIED INCH SCREW THREADS (UNJ THREAD FORM)
(E) EXAMPLE: 0.5000-20 UNJF-3A (22s); lead and angle control required -
0.4 PD tolerance. From Table 6 , allowable lead variation is O.ooo9 in. This would
be adjusted to 0.4/0.5 times O.ooo9 which is 0.0007 in. From Table 7, allowable angle variation is 1 degree 10 minutes
or 70 minutes. This would be adjusted to 0.4/0.5 times 70 which is 56 minutes or 55 minutes when rounded.
(d) For requirements of (a) and (b) above, lead variation values tabulated or calculated are the max- imum variations from specified lead between any two points not farther apart than the length of the max- imum-material (GO) thread gage. Flank angle vari- ation values are maximum variations from the basic 30 deg angle between thread flanks and perpendicu- lars to the thread axis.
ASME 61.15-1995
(e) Allowable variations in lead and flank angles are maximum values. Maximum variation in these and pitch diameter tolerance cannot be taken simul- taneously.
4.4.3 Runout of Major Diameter and Minor Di- ameter to Pitch Cylinders. When measurement is specified, maximum circular runout shall be limited to a full indicator movement equal to the pitch di- ameter tolerance.
4.4.4 Taper. If the pitch cylinder is conical, the difference in pitch diameters between the ends of the thread are an indication of taper. When measurement is required, it shall be specified. If not specified, al- lowable taper is no greater than the pitch diameter tolerance. &”

FOREWORD
(This Foreword is not part of ASME 81.15-1995.)
This Standard is similar to Military Specification MIL-S-8879 and equivalent to ISO- 3161-1977 for thread Classes 3A and 3B. British Standard BS 4084:1978 including Amend- ment 1 is technically identical to ISO-3161-1977 except for Appendix A which provides information for a 20 UNJ constant pitch series for diameters through 3 inches.
The UNJ thread form, having the enlarged root radius in the external thread, was introduced for applications requiring high fatigue strength where working stress levels are high, in order to minimize size and weight in parts, as in aerospace applications and also for other designs in commercial products where stresses are critical. To meet these requirements, the UNJ external thread root radius is designed between 0.1501 1P to 0. I8042P and the minor diameter of the mating internal thread is increased to ensure the necessary clearance.
This Standard includes Classes 2A and 2B UNJ screw threads. Either Class 3 or Class 2 UNJ threads are appropriate for commercial applications commensurate with the fatigue and stress levels required.
It is not recommended that Classes 2A and 2B threads be used for aerospace applications. Only UNJ thread Classes 3A and 3B meet the requirements of Military Specification MIL- S-8879.
NOTE: In what follows, the symbols H and h are used. H is defined as the height of the sharp vee thread formed by extending the thread flanks until they meet. H is equal to 0.866025 times the pitch, P. The symbol h is equal to 0.75 times H and represents the theoretical height of the American National thread form. It is still used as the basis for the value called percent of thread.
The UNJ thread form is the UN thread form modified to '/M H or 75% h basic thread depth which allows the 0.18042P maximum root radius in the external thread. The first known U.S. standard of similar thread form was the Society of Automotive Engineers Aeronautical Standard AS 82 published in March 1942, which is a modified American National thread form to 75% h basic thread depth and specifying 0.108P-0.18OP root radius in the external thread. This thread was symbolized NR, National Round, and was developed for aircraft engine applications.
Tension-tension fatigue testing of aircraft fasteners in 1942 demonstrated the importance of the external thread root contour in the fatigue life of a screw thread rolled after heat treatment. Fatigue testing isolated the following elements of good external thread root design:
The root should be radiused, not sharp.
Theoretically, it should be a continuous circular arc, blending smoothly with the thread flanks.
The radius should be as large as possible within the allowable design form.
The root contour should be smooth throughout, free of any imperfections, tool marks, or other minor notches.

Recognizing the need for improved 160,000 psi tensile strength bolts, the Military Services published in April 1952, MIL-B-7838A bolt procurement specification for aircraft applications based on the Unified thread form having 83’/3Vo h Unified thread form. Thus, larger external root radius requires a shallower internal thread depth to clear the flank tangency point. Although the Unified internal thread standards for tap drill sizes permit depths of more than 75% h, production rarely used these drills because deeper tapping of internal threads is generally not considered economically practical. A few internal threads have depths as great as 70% h, but the vast majority lie between 60% and 68% h.
Since internal threads are generally less than 75% h basic thread depth, the root radius of the external thread was increased to 0.150P min. and 0.18OP max. for the 180,000 psi and higher tensile strength bolts. This external thread form was developed in 1955 by the aerospace fastener industry and was known as the “Hi R” thread form.
Through the coordinated effort with the Aerospace Engine and Propeller Utility Stan- dards parts Committee E25 of SAE and the AIA National Aerospace Standards Committee NASC, the Air Force and Navy developed and published in September 1960, the thread specification MIL-S-8879 which features the “Hi R” thread root radius in the external thread and the internal thread modified to 9/16 H basic or 75% h thread depth.
With the advent of aircraft gas turbine engines, the high temperature threaded fasteners developed better elevated temperature performance using MIL-S-8879 UNJ thread root radius, in that the stress-rupture life of bolts was greatly improved.
The UNJ thread form has been adopted by the aerospace industry as the all-purpose thread standard, with the exception of electrical hardware and thread sizes 0.138 and smaller, which may use the UN thread form.
Suggestions for improvement of this Standard will be welcome. They should be sent to The American Society of Mechanical Engineers, Att: Secretary, B1 Main Committee, 345 East 47th Street, New York, NY 10017.
This Standard was approved as an ASME Standard on June 22, 1993.

ASME B l - 1 . 5 95 0759b70 0565759 bTb
ASME B1.15-1995
UNIFIED INCH SCREW THREADS (UNJ THREAD FORM)
SECTION 1 GENERAL
1.1 Scope
This Standard establishes the basic triangular pro- file for the UNJ thread form, provides a system of designations, lists the standard series of diameter- pitch combinations for diameters from 0.600 to 6.000 in., and specifies limiting dimensions and tolerances.
It specifies the characteristics of the UNJ inch series of threads having 0.1501 1P to 0.18042P designed ra- dius at the root of the external thread, and also having the minor diameter of the external and internal threads increased above the ASME B1.1 UN and UNR thread forms to accommodate the external thread maximum root radius.
1.2 Field of Application
The UNJ screw thread is designed for aerospace inch threaded parts, or for use on other highly stressed applications requiring high fatigue strength. For aero- space applications, only Classes 3A and 3B should be used.
1.3 Assembly
Threads conforming to the UN profile (ASME B1.1) and the UNJ profile are not interchangeable because of possible interference between the UNJ external thread minor diameter and the UN internal thread minor diameter. However, the UNJ internal thread will assemble with the UN external thread.
1.4 Federal Government Use
When this Standard is approved by the Department of Defense and federal agencies and is incorporated into FED-STD-H28/4, Screw Thread Standards for Federal Services, Section 4, the use of this Standard by the federal government is subject to all the re- quirements and limitations of FED-STD-H28/4.

ASME BL.15 75 W 0757670 0565760 314
UNIFIED INCH SCREW THREADS (UNJ THREAD FORM)
SECTION 2 PROFILE OF THREAD
2.1 Basic Profile
The basic profile is the theoretical profile corre- sponding to the basic dimensions of the thread major diameter, pitch diameter, and minor diameter. Profile applies to an axial plane. The basic profile is shown in Fig. 1.
2.2 Basic Thread Profile Symbols
The symbols used in the basic profile shown in Fig. 1 represent the following:
D bsc = basic major diameter of internal thread D2 bsc = basic pitch diameter of internal thread D, bsc = basic minor diameter of internal thread
d bsc = basic major diameter of external thread d2 bsc = basic pitch diameter of external thread d l bsc = basic minor diameter of external thread
H = height of fundamental triangle P = pitch
Appendix A provides a complete list of symbols applicable to the UNJ thread form.
2.3 Design Profiles
The design profile for the internal thread at max- imum-material conditions is the same as the basic profile, except in practice, the root is cleared above the basic major diameter, D bsc. See Fig. 2.
The design profile for the external thread at max- imum-material condition for Class 3A is the basic profile with a radiused minor diameter tangent to the
ASME 81.15-1995
flanks for the upper limit profile. For Class 2A, an allowance is applied to the basic profile, The external thread crest may be flat, partially or corner rounded, tangent to the 0.125P flat. See Fig. 3.
2.4 Root Radius of the Thread
2.4.1 InternalThread. For internal threads, the profile of the actual root of the thread shall at no point be below the basic profile. No root radius is specified.
2.4.2 External Thread. For external threads, the profile of the actual root of the thread shall lie within the root radius tolerance zone shown in Fig. 4. The limit dimensions of the root radius R as shown in Fig. 4 and their values are specified in Table 4. The profile shall be a continuous smoothly blended nonreversing curve, no part of which shall have a radius of less than 0.1501 1P and which is tangent to the thread flanks at not less than 0.5625H basic thread depth. The profile may comprise tangent flank circular arcs that are tangent to the flanks and a flat at the minor diameter provided that the minor diameter, d3, is within the zone established in Fig. 4.
2.4.3 Incomplete Threads. Unless otherwise specified, the runout threads on externally threaded parts shall be no less than 1, nor more than 2 pitches in length. The threads shall run-out onto the shank without any abrupt change in cross-sectional area. The root radius shall be no less than the minimum radius of the full thread section.

UNIFIED INCH SCREW THREADS (UNJ THREAD FORM)
SECTION 4 THREAD CHARACTERISTICS
4.1 Length of Thread Engagement, LE
Tolerances specified in Table 5 are based on a length of engagement equal to the basic major diameter for the UNJC, UNJF, and 8-UNJ series and are appli- cable for length of engagement up to 1.5 diameters; and a length of engagement of 9 pitches for the UN- JEF, 12-UNJ, and 16-UNJ series, and are applicable for lengths of engagement of 5 to 15 pitches.
For lengths of engagement over 1.5 (to and in- cluding 3 diameters) or over 15 (to and including 30 pitches), the pitch diameter tolerances are 1.25 times the tabulated values. For lengths of engagement over 3 diameters or 30 pitches, the pitch diameter toler- ances are 1.5 times the tabulated values.
In addition to increasing pitch diameter tolerances for long lengths of engagement, maximum-material gages (GO) used for acceptance shall be equal in length to the design length of engagement.
4.2 Tolerance System
The system of tolerances and allowances is based on ASME B1.1 inch screw thread system of tolerance classes. Tolerances and allowances are applied plus for internal threads and minus for external threads.
4.3 Limits of Size
The basic profile dimensions are given in Table 1. The profile dimensions and tolerances ( T ) shown in Figs. 2 and 3 and their values for the standard series are specified in Table 5. For special threads for which there are no tabulated values, use the formulas in paras. 4.3.1 through 4.3.4, together with the tolerance table in Appendix B. Constants for the special thread formulas are given in Table 3.
NOTE: The dimensions and tolerances listed in Table 5 have been calculated and rounded to the procedures specified in ASME Bl.30. As a consequence, a few of the values listed vary from 0.0001 in. to 0.0002 in. from listed values in previously issued standards for UN and UNJ inch threads.

UNIFIED INCH SCREW THREADS (UNJ THREAD FORM)
4.4 Thread Form Tolerances
4.4.1 Cumulative form variation is the combined effect on functional size due to individual thread form variations in lead (pitch), helix, flank angle, taper, and roundness.
When measurement is specified for Classes 3A and 3B threads, cumulative form tolerance shall be 0.5 times pitch diameter tolerance. If not specified, con- trol shall be by the required system gages.
4.4.2 Lead and Flank Angle Variations (U) When individual inspection of lead (including
helix) and flank angle variations are required, the allowable variations for these characteristics shall be in accordance with Tables 6 and 7 unless otherwise specified.
(b) For sizes not included in Tables 6 and 7, the allowable lead variation is equal to 0.57735 times one- half the pitch diameter tolerance. This is the lead variation which causes a change in functional diam- eter equal to 0.5 times the pitch diameter tolerance. The allowable flank half-angle variation in minutes of arc is equal to 30 plus 1.875 times the number of threads per inch rounded to the nearest 5 minutes for 32 threads per inch and coarser, and 62 plus 0.775 times the number of threads per inch rounded to the nearest 5 minutes for threads finer than 32 threads per inch.
EXAMPLE: 0.945-8.5 UNJS-3A; lead and angle control required. No lead and angle tolerances were specified nor do default values
appear in Tables 6 and 7. Values are calculated as follows: Lead tolerance = 0.57735 X 0.5 Td, Pitch diameter tolerance Td2 = 0.0050 Lead tolerance = 0.57735 x 0.5 x 0.0050 = 0.0014 in. Angle tolerance (for coarser than 32 tpi) = 30 + (1.875 x tpi) Angle tolerance = 30+ (1.875 x 8.5)
= 45.94 minutes = 45 minutes when rounded to nearest 5 minutes
EXAMPLE: 0.500-41 UNJS-3B; lead and angle control required. Lead tolerance = 0.57735 X 0.5 Td2 Pitch diameter tolerance Td, = 0.0031 Lead tolerance = 0.57735 x 0.5 x 0.003 1 = 0.009 in. Angle tolerance (for finer than 32 tpi) = 62 + (0.775 X tpi) Angle tolerance = 62 + (0.775 x 41)
=93.78 minutes = 1 degree and 35 minutes when rounded to near-
est 5 minutes
(C) If lead and angle tolerances are specified as a pitch diameter equivalent in terms of pitch diameter tolerance, tolerances in accordance with para. 4.4.2(a) or para. 4.4.2(b) may be adjusted proportionately using 0.5 times pitch diameter tolerance as a basis.

ASME B L - L 5 95 0759b70 05b57bb 836 D
UNIFIED INCH SCREW THREADS (UNJ THREAD FORM)
EXAMPLE: 0.5000-20 UNJF-3A (22s); lead and angle control required -
0.4 PD tolerance. From Table 6 , allowable lead variation is 0.0009 in. This would
be adjusted to 0.4103 times 0.009 which is 0.0007 in. From Table 7, allowable angle variation is 1 degree 10 minutes
or 70 minutes. This would be adjusted to 0.4103 times 70 which is 56 minutes or 55 minutes when rounded.
(d) For requirements of (a) and (b) above, lead variation values tabulated or calculated are the max- imum variations from specified lead between any two points not farther apart than the length of the max- imum-material (GO) thread gage. Flank angle vari- ation values are maximum variations from the basic 30 deg angle between thread flanks and perpendicu- lars to the thread axis.
ASME 81.15-1995
(e) Allowable variations in lead and flank angles are maximum values. Maximum variation in these and pitch diameter tolerance cannot be taken simul- taneously.
4.4.3 Runout of Major Diameter and Minor Di- ameter to Pitch Cylinders. When measurement is specified, maximum circular runout shall be limited to a full indicator movement equal to the pitch di- ameter tolerance.
4.4.4 Taper. If the pitch cylinder is conical, the difference in pitch diameters between the ends of the thread are an indication of taper. When measurement is required, it shall be specified. If not specified, al- lowable taper is no greater than the pitch diameter tolerance.

UNIFIED INCH SCREW THREADS (UNJ THREAD FORM) ASME B1.15-1995
SECTION 5 DIMENSIONAL ACCOMMODATION OF COATINGS AND PLATINGS
The general rules for calculation of coating allow- ance are defined in Appendix C. Restrictions in paras. 5.1 through 5.5 also apply.
5.1 Coated External Threads - Class 3A
Coated or plated external threads with a pitch di- ameter tolerance of 0.0035 in. or less may have the minimum pitch diameter specified in Table 5 reduced by not more than 0.0010 in. The major and minor diameter limits specified in Table 5 may be reduced by not more than 0.0005 in. When the pitch diameter tolerance exceeds 0.0035 in., the minimum pitch di- ameter may be reduced by 0.3 times the pitch diameter tolerance, but this reduction shall not exceed 0.0015 in. The major and minor diameter limits may be re- duced by not more than 0.0008 in. The material limits for coated external threads shall be as specified herein. All thread elements shall be within the size limits specified in Table 5.
5.2 Coating Threads With Dry Film Lubricant
Threads to be coated with a dry film lubricant may have the standard coating allowance applied as spec-
ified in paras. 5.1 and 5.4. If the standard coating allowance is utilized, the threads shall conform to the specified limits of size after coating. If another coat- ing is applied before dry film lubricant, no allowance shall be allowed to accommodate the dry film lubri- cant, and inspection should be accomplished before coating.
5.3 Coated External Threads - Class 2A
The external thread material limits may not be re- duced beyond the minimum material limits to accom- modate coating. After coating, the threads shall be no larger than Class 3A material limits specified in Table 5 .
5.4 Coated Internal Threads - Classes 26 and 38
For coated or plated internal threads, the maximum values of minor diameter and pitch diameter specified in Table 5 may be increased by the same amount permitted in para. 5.1 for external thread decrease. The limits for coated or plated internal threads shall be within the values specified in Table 5.

SECTION 6 DESIGNATION OF THREADS
ASME 81.15-1995
6.1 Basic Desianation Ifl Internal Thread, Runout Control 1.5ooO-18 UNJEF-3B (21s)
Unified inch screw threads are identified with the Runout variation - 0.5 PD Tol. letters UN in the thread designation. The inch screw thread described in this Standard is designated by the letters UNJ to identify the inch J thread form. 6.3 Designation of Coated Threads
6.2 Standard Thread Series Designation
Standard threads shall be designated by indicating in sequence the nominal size, the number of threads per inch, the thread series symbol, and the thread class symbol. The gaging system designator depicted in the examples may be designated at each thread callout as shown, or as a general note on the drawing, specification sheet, or applicable document.
EXAMPLES: ( a ) External Thread, Right Hand
1 lTh!ds\r inch
0.2500-20 UNJC-3A (22) LInspection system
External thread class symbol
Coarse pitch series symbol
Nominal size (basic major diameter)
( b ) Infernal Thread, Right Hand
I lTh!ac!per inch
3.5000-12 UNJ-2B (21) LInspection system
Internal thread class symbol
Constant pitch series symbol
Nominal size (basic major diameter)
( C ) External Thread, Left Hand 0.9375-20 UNJEF-3A-LH (22)
( d ) External Thread, Cumulative Form Control
Cumulative form variations - 0.5 PD Tol.
( e ) External Thread, Angle and Lead Control
1.6250-12 UNJ-3A (22s)
3.7500-16 UNJ-2A (22s) Lead and angle control required
Coated threads shall be designated by only the standard thread designation where the coating allow- ances given in Section 5 are adequate relief for the applied coating. Unless otherwise specified, threaded parts to be coated shall have the standard coating allowances specified in para. 5.1 for external threads and para. 5.4 for internal threads. The thread limits shall be within tolerance, as modified by the coating allowance, before coating. After coating, the material limits in Table 5 for standard UNJ thread shall apply.
6.4 Designation of Threads Having Modified Crests
Where the limits of size of the major diameter of an external thread or the minor diameter of an internal thread are modified, the thread designation is suffixed by the letters MOD, followed by the modified di- ameter limits.
EXAMPLE: External thread, major diameter reduced 0.003 in. 0.2500-28 UNJF-3A MOD (22) Major diameter 0.2405-0.2470 MOD
EXAMPLE: Internal thread, minor diameter increased 0.003 in. 0.2500-28 UNJF-3B MOD (21) Minor diameter 0.2182-0.2259 MOD
6.5 Designation of Threads Having Special Length Requirements
Where a standard series thread has a special length of engagement differing from that for which the standard pitch diameter tolerances are applicable, the thread class symbol is prefixed by the letters SE (Spe- cial Engagement) followed by the special pitch di- ameter limits of size, in accordance with para. 4.1, and the length of engagement ( L E ) .

APPENDIX C COATING OF THREADS
(This Appendix is not part of ASME 81.15-1995 and is included for information only.)
Coating is one or more applications of additive finish of any material including Dry Film lubricants, but not including soft or liquid lubricant. On a cylindrical surface, the effect of coating is to change the diameter by twice the coating thickness - one coating thickness on each side of the cylinder. Because the coating thickness is measured per- pendicular to the coated surface while the pitch diameter is measured perpendicular to the thread axis, the effect of a uniformly coated thread flank on the pitch diameter is a change four times the thickness of coating on the flank.
The diameters of external threads before coating will be smaller while the diameters of internal threads before coating will be larger than the coated diameters.
( a ) External Thread - Maximum and Minimum Coating Thickness Specified. To determine before coating gaging limits, for a uniformly coated thread, decrease:
(1) maximum pitch diameter by four times maximum coating thickness; (2) minimum pitch diameter by four times minimum coating thickness; (3) maximum major diameter by two times maximum coating thickness; (4) minimum major diameter by two times minimum coating thickness.
( b ) Nominal orMinimum Coating Thickness Specified. If no coating thickness tolerance is given, it is recommended that a tolerance of plus 50% of the nominal or minimum thickness be assumed. Then, to determine before coating gaging limits for a uniformly coated thread, decrease:
(1) maximum pitch diameter by six times coating thickness; (2) minimum pitch diameter by four times coating thickness; (3) maximum major diameter by three times coating thickness; (4) minimum major diameter by two times coating thickness.
(C) Internal Threads. Standard internal threads provide no allowance for coating thick- ness. To determine before coating gaging limits for a uniformly coated thread, increase:
(1) minimum pitch diameter by four times maximurn coating thickness, if specified, or by six times minimum or nominal coating thickness, when a tolerance is not specified;
(2) maximum pitch diameter by four times minimum or nominal coating thickness; (3) minimum minor diameter by two times maximum coating thickness, if specified,
(4) maximum minor diameter by two times minimum or nominal coating thickness. ( d ) Other considerations are essential to adequately review all possibilities and consider
limitations in the threading and coating production processes before finalizing the coating process and the allowance required to accommodate the coating. A no allowance thread after coating shall not transgress the basic profile and is, therefore, subject to acceptance using a basic size GO thread gage.
or by three times minimum or nominal coating thickness;
