(Specification)Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength
Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength
ABSTRACT
This specification covers two types of quenched and tempered, steel, metric heavy hex structural bolts. The bolts are intended for use in structural connections. The bolts are furnished in sizes M12 to M36 inclusive. They are designated by type denoting chemical composition as follows: Type 1—Medium-carbon, carbon boron, medium carbon alloy, or alloy boron steel; and Type 3—Weathering Steel. Materials shall be tested and the individual grades shall conform to specified values of heat treatment, threading, hot-dip and mechanically coated zinc coatings, lubrication, secondary processing, chemical composition, mechanical properties such as hardness, tensile properties, and rotational capacity.
SCOPE
1.1 This specification2 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 comparable to those covered under the requirements of the Specification for Structural Joints Using High-Strength 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:

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Withdrawn in November 1991.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 A449. Also refer to Specification A449 for quenched and tempered steel bolts and studs with diameters greater than 11/2 in. but with similar mechanical properties.
1.4 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.Note 2—A complete metric companion to Specification A325 has been developed, Specification A325M; therefore, no metric equivalents are presented in this specification.
1.5 This specification is applicable to heavy hex structural bolts only. For bolts of other configurations and thread lengths with similar mechanical properties, see Specification A449.
1.6 Terms used in this specification are defined in Terminology F1789.
1.7 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.
