Summary


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.


Supplementary Requirements

 

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 AA Anchor Bolt, Inc. will be used




® AA Anchor Bolt Inc.

** 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

36
AB36
55
AB55
105
AB105

 

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

-  Stamping of F1554 bolts is part of Supplemental Requirement S2 while color-coding is required regardless.

-   When F1554 Grade 36 is specified, a weldable F1554 Grade 55 may be furnished at the supplier’s option.


Recommended Nuts and Washers


According 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:
