ASTM F1554

Quick Links

Scope

The ASTM F1554 specification was introduced in 1994 and covers anchor bolts designed to anchor structural supports to concrete foundations. F1554 anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. The three grades 36, 55, and 105 designate the minimum yield strength (ksi) of the anchor bolt. 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.

GRADES

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

MECHANICAL PROPERTIES

Grade	Size inches	Tensile, ksi	Yield, ksi min	Yield, MPa min	Elong. % min	RA % min
36	1/4 - 4	58 - 80	36	248	23	40
55	1/4 - 2	75 - 95	55	380	21	30
	2¼ - 2½	75 - 95	55	380	21	22
	2¾ - 3	75 - 95	55	380	21	20
	3¼ - 4	75 - 95	55	380	21	18
105	1/4 - 3	125 - 150	105	724	15	45
Stamping of F1554 bolts is a supplemental requirement (S2) while color coding is required. When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier's option.

RECOMMENDED NUTS and WASHERS

Grade	Size inches	Plain	Galvanized	Washer
36	1/4 - 1-½	A563A Hex	A563A Hex	F436
36	1-¾ - 4	A563A Heavy Hex	A563A Heavy Hex	F436
55	1/4 - 1-½	A563A Hex	A563A Heavy Hex	F436
