Anchor Bolts

Anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. There are three grades 36, 55, and 105 designate the minimum yield strength (ksi) of the anchor bolt under ASTM F1554 Specification. The bolts can be either cut or roll threaded and a weldable grade 55 can be substituted for grade 36 at the supplier’s option. Color coding on the end - 36 blue, 55 yellow, and 105 red – helps facilitate easy identification in the field. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements.

Applications for F1554 anchor bolts include columns in structural steel framed buildings, traffic signal and street lighting poles, and overhead highway sign structures to name just a few.

Anchor Bolt Grades

F1554 Grade 36	Low carbon, 36 ksi yield steel anchor bolts
F1554 Grade 55	High strength, low alloy, 55 ksi yield steel anchor bolts
F1554 Grade 105	Alloy, heat treated, high strength 105 ksi yield steel anchor bolts
