ASTM A325-06

Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength

SCOPE
1.1 This specification covers two types of quenched and tempered steel heavy hex structural bolts having a minimum tensile strength of 120 ksi for sizes 1.0 in. and less and 105 ksi for sizes over 1.0 to 11/2 in., inclusive.
1.2 The bolts are intended for use in structural connections. These connections are covered under the requirements of the Specification for Structural Joints Using ASTM A 325 or A 490 Bolts, approved by the Research Council on Structural Connections, endorsed by the American Institute of Steel Construction and by the Industrial Fastener Institute.
1.3 The bolts are furnished in sizes 1/2 to 11/2 in., inclusive. They are designated by type, denoting chemical composition as follows:Type Description Type 1 Medium carbon, carbon boron, or medium carbon alloy steel. Type 2 Withdrawn in November 1991. Type 3 Weathering steel. Note 1—Bolts for general applications, including anchor bolts, are covered by Specification A 449. Also refer to Specification A 449 for quenched and tempered steel bolts and studs with diameters greater than 11/2 in. but with similar mechanical properties.
Note 2
A complete metric companion to Specification A 325 has been developed-Specification A 325M; therefore, no metric equivalents are presented in this specification.
1.4 This specification is applicable to heavy hex structural bolts only. For bolts of other configurations and thread lengths with similar mechanical properties, see Specification A 449.
1.5 Terms used in this specification are defined in Terminology F 1789.
The following safety hazard caveat pertains only to the test methods portion, Section 10, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
