Work Item
ASTM WK97151
Revision of F3125/F3125M-25 Standard Specification for High Strength Structural Bolts and Assemblies, Steel and Alloy Steel, Heat Treated, Inch Dimensions 120 ksi, 144 ksi, and 150 ksi Minimum Tensile Strength, and Metric Dimensions 830 MPa and 1040 MPa Minimum Tensile Strength
Rationale
Supplementary Requirement S2 was originally intended to make possible the use of alternative lengths (bolt and/or threads), and alternative head styles or dimensions to accommodate occasional non-standard purchaser needs. It was always intended for such alternatives products to meet all the requirements in F3125/F3125M. However, the current wording is not explicit relative to the requirements and is misinterpreted to permit the use of bolts with countersunk heads, under the mistaken assumption they can meet all the requirements of F3125/F3125M. The proposed revision of S2 aims to explicitly clarify the requirements.
