ASTM F1554 is the newest construction fastener specification developed by the American Society for Testing and Materials and covers steel anchor bolts intended for anchoring structural supports to concrete foundations. Chemical requirements, mechanical properties, and dimensional tolerances are all covered under the F1554 specification.

Grades

ASTM F1554 consists of three grades that correspond to the minimum yield strength of the steel. These grades are as follows:

• F1554 grade 36 – 36 ksi minimum yield strength.
• F1554 grade 55 – 55 ksi minimum yield strength.
• F1554 grade 105 – 105 ksi minimum yield strength.

Configuration

Product Identification and Marking

The end of each anchor bolt intended to project from the concrete requires a color code to identify the grade as follows:

Permanent manufacturer’s identification markings (Supplementary Requirement S2) and/or permanent grade identification markings (Supplementary Requirement S3) can be specified on the inquiry and purchase order. However, only color coding is required. When one or both of the supplementary requirements are specified, the end of the anchor bolt intended to project from the concrete shall be steel die stamped. Grade identification markings are as follows:

  

Dimensional Criteria

Body Diameter: Both full-bodied cut thread anchor bolts or reduced-bodied roll thread anchor bolts are acceptable, and either can be supplied at the discretion of the manufacturer (unless otherwise specified).
