A325/A325M History

This specification covers two types of quenched and tempered, steel, metric heavy hex structural bolts having a minimum tensile strength of 830 MPa (Note 1).

 

Formerly under the jurisdiction of Committee F16 on Fasteners, this specification was withdrawn in May 2016 and replaced by Specification F3125/F3125M for High Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120 ksi (830 MPa) and 150 ksi (1040 MPa) Minimum Tensile Strength, Inch and Metric Dimensions. Specification F3125/F3125M supersedes and replaces specifications; A325, A325M, A490, A490M, F1852 and F2280. The unified Specification F3125/F3125M corrects known inconsistencies in the original documents and the combination will assure that requirements of the products covered under the original standards stay aligned.

Product Description
The most common heavy hex head screw, these steel screws meet ASTM A325 regulations for
structural joints, such as mating I-beams and scaffolding. Material meets ASTM F3125
specifications for quality. Dimensions meet ASME B18.2.6 specifications. 
Partially threaded screws come with precise threaded and unthreaded portions, allowing you to place
only the stronger unthreaded portion (grip) in joints subjected to sideways forces.
Hot-dipped galvanized screws have a thick coating for excellent corrosion resistance. To ensure
compatibility, use these screws with hot-dipped galvanized steel nuts.
