ASTM A307 Standard Specification for Carbon Steel Bolts and Studs, 60 000 PSI Tensile Strength
This specification covers the chemical and mechanical requirements for three grades (Grades A, B, and C) of carbon steel bolts and studs in specified sizes. This specification does not cover the requirements for machine screws, thread cutting/forming screws, mechanical expansion anchors, or other similar externally threaded fasteners. When tested, sampled specimens shall adhere to specified values for chemical composition, hardness, tensile strength, yield point, elongation, and dimensions.
1. Scope
1.1 This specification covers the chemical and mechanical requirements of three grades of carbon steel bolts and studs in sizes ¼ in. through 4 in. The fasteners are designated by “Grade” denoting tensile strength and intended use, as follows:
