F1554 Grade 55OverviewASTM F1554 grade 55 anchor bolts are manufactured from a modified mild steel that has a higher minimumyield strength (55 ksi) than traditional A36 mild steel (36 ksi). This specification was widely used in the lightpole and traffic signal industry long before the ASTM F1554 specification was introduced in 1994 and wascommonly referred to as A36M55. Just as with grade 36, grade 55 covers anchor bolts in diameters rangingfrom 1/4" through 4".
Galvanizing
F1554 grade 55 anchor bolts can be provided in either a black or galvanized condition.
Welding
Contrary to popular belief, not all grade 55 material is weldable. If weldability is required, supplementaryrequirement S1 must be specified. A weldable grade 55 may be substituted at the supplier's option whengrade 36 is specified. All of the grade 55 round bar that Portland Bolt stocks will meet the S1 weldabilityrequirements.
Supplementary TestingA supplementary requirement S4 also exists which designates Charpy Impact testing requirements.
Material Substitution
Be skeptical of fastener distributors and manufacturers with limited manufacturing capabilities who attempt tosubstitute 1045 round bar or even A193 grade B7 material for F1554 grade 55. These materials and othergrades of steel may exceed the tensile and yield requirements of the F1554 grade 55 specification, but willusually not meet the elongation and reduction of area requirements. Grade 55 round bar is notcommonly available through local warehouses. Portland Bolt buys mill runs of round bar and stocks thismaterial for immediate processing.

Typically have a nut and/oranchor plate embedded inthe concrete foundation toprovide pull-out resistance.The nut and/or plate areoften welded to the bottom ofthe anchor rod. Fullythreaded rods can be usedwith epoxy in preexistingconcrete slabs.
Anchor Rods
These anchor bolts have a90° bend (right angle bend)that provides pull-outresistance. The smooth rodis bent to form an "L" shapedhook and is embedded in theconcrete. This designprovides the anchorage.
Bent Anchor Bolts
Headed bolts are turnedupside down and poured intoa concrete foundation withthe threads projecting fromthe concrete and the headproviding pull-out resistance.A square or round plate isoften welded to the head ofthe bolt (for grades 36 and55) to provide additionalstrength.
Headed AnchorBolts
ConfigurationASTM F1554 anchor bolts can be straight rods (either fully threaded or threaded on each end), bent anchorbolts, or headed bolts.

1 A563 grade D nuts are rarely available. A563 grade DH or A194 grade 2H should be substituted.2 The availability of A563 grade DH nuts in nominal sizes 1" and larger is very limited and generally available only on specialorders of 50,000 or more. For smaller quantities, ASTM A194 grade 2H should be considered.
