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:

AB55 |
105 |
AB105 |
** When S2 and/or S3 are required, it must be specified on the inquiry and purchase order.
