PLEASE NOTE:The new F3125 specification is a consolidation and replacement of six ASTM standards, including; A325, A325M, A490, A490M, F1852 (A325 TC), and F2280 (A490 TC). Until the F3125 specification is more widely used and until the A325 and A490 specifications have been eliminated by ASTM, we will continue to manufacture and sell A325 and A490 heavy hex structural bolts under their existing specification requirements, unless F3125 is referenced in the inquiry and/or purchase order.
ASTM F3125 Grade F1852 (A325 TC)
Structural bolts, steel, heat treated, 120 ksi minimum tensile strength.
The ASTM F3125 Grade F1852, (Also known as A325 TC bolts) specification cover heat treated, steel, tension control bolt-nut-washer assemblies, also referred to as “sets.” These assemblies are capable of developing a minimum predetermined tension when installed by applying torque to the nut, while at the same time applying a counter torque to separate the spline end from the body of the bolt using an appropriate spline drive installation tool.
Formerly under the jurisdiction of Committee F16 on Fasteners, the F1852 specification was withdrawn in May 2016 and replaced by Specification F3125 for High Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120 ksi Minimum Tensile Strength, Inch and Metric Dimensions.
