• DIN 1481 is interchangeable with ISO 8752 (EN 28752) except fora variation in length tolerance.

• The ASME 18.8.2 range meets the requirement of NASM10971 (formerly MIL-P-1091), NASM 16562 (formerly 16562),

NAS 561, SAE J496, and SAE AS7207 (Superseded AMS 7207and MS 17140-17190).

• ISO 13337 (DIN 7346), lightweight Slotted Pins, are available made-to-order for volume applications.

ISO 9002 and QS-9000 Certificationsare your guarantee for consistent quality.

� Contract Review / Quality Planning. A formal procedureexists for the specification and acceptance of new orders bysales, manufacturing and quality.

� Document / Drawing Control. All drawings, standards andspecifications are controlled through engineering.

� SQA Approval of Suppliers and Subcontractors ismaintained by supplier system audits and monitoring ofsupplier quality performance.

� System Audits are carried out regularly by independentauditors with written reports submitted for management action.

� Calibration and Gauge Control. All gauges are calibratedon a regular basis, traceable back to national standards. Thecontrol records are computerized.

� All parts are traceable through each manufacturing processand heat treatment back to the original raw material testcertificate. Each lot has a unique identification number on thepackaging which should be retained by the customer andquoted in the event of any inquiry.

� Manufacturing Controls. There is clear identification of joband quality status with controlled routings. Capability studiesare used to verify machine and process capability; statisticalprocess control is used for all processes, using variable andattribute data; and there are final audit checks of completedparts and stock.

� Non-Conforming Parts. These are segregated with a "hold"label and quarantined pending a decision on disposal. Anautomated corrective action system ensures managementcontrol for quick and accurate responses to customer inquiries.

THE CHOICE – ASME OR ISO

SPIROL produces Slotted Pins to both the American National Standard, ASME B18.8.4M and the InternationalStandard, ISO 8752 (EN 28752). It is our recommendation that you consider ASME pins for all new applications andfor your current applications if you are experiencing insertion problems or performance failures. Our recommendationis based on these important advantages of ASME pins:

� LOWER INSERTION FORCE as a result of the smaller free diameter of the pin in relation to the nominal hole. The pin issecurely retained in the hole based on increased wall thickness, higher minimum hardness, and the minimal slot afterinsertion.

� NO INTERLOCKING because the maximum gap in the free diameter state is always less than the wall thickness of the pin.

� HIGHER SHEAR STRENGTH based on increased wall thickness, a higher minimum hardness, and narrower slots whichclose under load to ensure that the pins fail instantaneously rather than progressively in shear.

COMPARISON OF TECHNICAL SPECIFICATIONS

COMPARISON OF RECOMMENDED HOLES

ASME pins 3 mm and larger can besubstituted for ISO pins without anyreview or change. 1.5 to 2.5 mmpins require a change in themaximum specified hole.

ASME recommends tolerance classH10 for holes up to 2.5 mm and H12for diameters 3 mm and larger. ISOrecommends H12 for all diameters.

Nom. Dia. ISO ASME

1.5 1.5 / 1.6 1.5 / 1.562 2 / 2.1 2 / 2.07

2.5 2.5 / 2.65 2.5 / 2.583 and up No difference No difference

EXPANDED DIAMETER – ASME pins have a smallerexpanded or free diameter relative to the nominal hole.

CHAMFER SPECIFICATION – ASME specifies a maximumchamfer diameter from 0.1 to 0.5 mm smaller than the nominalhole diameter whereas ISO only specifies a chamfer diameterless than the nominal hole diameter. ASME specifies aminimum and maximum chamfer length whereas the chamferlength in ISO is only a reference dimension.

STRAIGHTNESS – ASME specifies a straightness requirement.ISO does not address it at all.

SHEAR STRENGTH – ASME specifies a minimum doubleshear strength for austenitic stainless steel. ISO does not.

MATERIAL – ASME includes Beryllium Copper. ISO does not.

LENGTH TOLERANCE – The differences are minimal:

WALL THICKNESS – ASME pins have a wall thickness equalto or greater than ISO pins and a greater cross sectional areabased on both thickness and strip width.

HARDNESS – The ASME specification for carbon steel ishigher (HV 458-560 vs HV 420-520) to maximize the tensilestrength and for chrome stainless it is slightly lower (HV 423-544 vs HV 440-560) to avoid the risk of brittleness.

RECOMMENDED PIN/SHAFT RATIOThe recommended maximum ratio is 1 to 3; that is the pindiameter should never exceed 33.3% of the shaft diameter. Ifthis limit is exceeded, the remaining material in the shaft isinadequate and the shaft will fail before the pin.

DOUBLE PINNINGIn situations requiring exceptionally high shear strength, it ispossible to use pins in combination by driving an inner pin intoan already inserted outer pin. The gaps should be 180°opposed. The recommended hole needs to be increased. It issuggested you consult Spirol Application Specialists in thesesituations.

WHICH STAINLESS?Martensitic chrome stainless is hardened and has strengthcomparable to carbon steel and satisfactory corrosionresistance in most cases. Austenitic nickel stainless steel hasbetter corrosion resistance in some environments but since it isnot hardened, it has lower strength and requires more care inthe insertion process.

HOLE PREPARATIONHoles can be drilled, punched or cast with no need foradditional reaming or sizing. Care should be taken to avoidundersize holes to eliminate potential pin damage duringinsertion. The following points are suggested for yourconsideration:

� Break or debur the edges, particularly in case of hardenedholes.

� Countersinking is not recommended if it increases theclearance at the shear plane.

� In case of cast or sintered metal holes, provide a lead-inradius.

� Whenever possible, punched holes should be punched inthe same direction as the direction of pin insertion.

� Eliminate hole misalignment problems by drilling holestogether.

� In case of hardened collars or similar components, flattenthe component at the entry of the hole to avoid two-pointcontact as the pin starts into the hole.

Shear values specified will only be obtained under theconditions noted in the referenced standards. Of special note:

� The clearance at the shear plane cannot exceed 0.15 mmor .005”.

� The hole has to be the nominal pin diameter (tolerance H6)with a hardness of not less than HV 700.

� The pin must be installed with the slot up.� The shear planes have to be at least one pin diameter from

each end, and at least two diameters apart.

STRAIGHTNESS SPECIFICATION(ASME PINS ONLY)The straightness over the length of the pins shall be such thatthe pin will pass freely through a ring gauge of the length anddiameter as specified below.
