A307-04 - Standard Specification for Carbon Steel Bolts and Studs, 60 000 PSI Tensile Strength
Description:
This specification covers the chemical and mechanical requirements of three grades of carbon steel bolts and studs in sizes 1/4 in. (6.35 mm) through 4 in. (104 mm). The fasteners are designated by "Grade" denoting tensile strength and intended use, as follows:
Grade Description
Grade A Bolts and studs having a minimum tensile strength of 60 ksi (414 MPa) and intended for general applications,
Grade B Bolts and studs having a tensile strength of 60 to 100 ksi (414 to 690 MPa) and intended for flanged joints in piping systems with cast iron flanges, and
Grade C Nonheaded anchor bolts, either bent or straight, having properties conforming to Specification A 36/A 36M (tensile strength of 58 to 80 ksi (400 to 550 MPa)) and intended for structural anchorage purposes.
