ASTM A307-03

Standard Specification for Carbon Steel Bolts and Studs, 60 000 PSI Tensile Strength

SCOPE
1.1 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 DescriptionGrade 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, andGrade C Nonheaded anchor bolts,
either bent or straight, having
properties conforming to
Specification A 36 (tensile
strength of 58 to 80 ksi (400
to 550 MPa)) and intended
for structural anchorage purposes.
1.1.1 The term studs includes stud stock, sometimes referred to as threaded rod.
1.2 This specification does not cover requirements for machine screws, thread cutting/forming screws, mechanical expansion anchors or similar externally threaded fasteners.
1.3 Suitable nuts are covered in Specification A 563. Unless otherwise specified, the grade and style of nut for each grade of fastener, of all surface finishes, shall be as follows: Fastener Grade and Size Nut Grade and Style A, C, 1/4 to 1 1/2 in.A, hex A, C, over 1 1/2 to 4 in.A, heavy hex B, 1/ 4 to 4 in.A, heavy hex  Nuts of other grades and styles having specified proof load stresses (Specification A 563, Table 3) greater than the specified grade and style of nut are also suitable.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 Supplementary Requirement S1 of an optional nature is provided, which describes additional restrictions to be applied when bolts are to be welded. It shall apply only when specified in the inquiry, order, and contract.
