Anchor Bolts - Power Manufacturing

Specifications

F1554 was introduced in 1994. This is the newest fastener specification by the American Society for Testing and Material (ASTM). F1554 covers anchor bolts designed to anchor structural supports to concrete foundations. The chemical requirements, mechanical properties, and dimensional tolerance are all encompassed under the F1554 specifications.

F1554 anchor bolts can be manufactured with cut or rolled threads per the customer’s specifications.

Grades

F1554 Grade 36	Low carbon, 36 ksi minimum yield strength.
F1554 Grade 55	Low alloy, 55 ksi minimum yield strength.
F1554 Grade 105	Alloy, heat-treated, high strength 105 ksi minimum yield strength.

S1. Grade 55 Bars & Anchor Bolts

The material that is covered under Supplementary Requirement S1 is suitable for welding. S1 confirms the material is suitable for welding by the restrictions for the chemical composition, and the carbon equivalent formula.

S2. Permanent Manufacturer’s Identification

When permanent manufacturer’s identification (S2) is required, the end of the anchor bolt protruding from the concrete shall be steel die stamped. The following identification marker, designed specifically for Power Manufacturing, LLC. will be used.

** When S2 and/or S3 are required, it must be specified on the inquiry and purchase order.

S3. Permanent Grade Identification

Permanent grade identification markers (S3) are utilized to readily identify the grade. The end of each anchor bolt above the concrete level requires a color code as follows:

F1554 Grade 36	F1554 Grade 55	F1554 Grade 105

When permanent grade identification is required, the end of the anchor bolt projecting from the concrete shall be steel die stamped. The grade identification markings are as follows:

Grade	Identification
36	AB36
55	AB55
105	AB105

** When S2 and/or S3 are required, it must be specified on the inquiry and purchase order.

Recommended Nuts and WashersAccording to the ASTM manual, unless otherwise specified, all nuts used on these anchor bolts shall conform to the requirements of Specification A194 or A563. Nuts shall be of the grade, surface finish, and style for each grade and size of anchor bolt as follows:

Grade	Size	NUTS – Plain	NUTS – Galvanized	Washers
36	1/4″-1-1/2”	A563A Hex	A563A Hex	USS, SAE, F436
36	1-5/8” – 4”	A563A Heavy Hex	A563A Heavy Hex	USS, SAE, F436
55	1/4″ – 1-1/2”	A563A Hex	A563A Heavy Hex	USS, SAE, F436
55	1-5/8” – 4”	A563A Heavy Hex	A563A Heavy Hex	USS, SAE, F436
105	1/4” – 1-1/2”	A563D Hex¹	A563DH Heavy Hex¹	F436
105	1-5/8” – 3”	A563DH Heavy Hex¹	A563DH Heavy Hex¹	F436

1. A563-D rarely available, A563DH or A194-2H can be substituted
