ASTM A490-00

Standard Specification for Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength

SCOPE
1.1 This specification covers two types of quenched and tempered, alloy steel, heavy hex structural bolts having a tensile strength of 150 to 173 ksi.
1.2 These bolts are intended for use in structural connections. These connections are covered under the requirements of the Specification for Structural Joints Using Specification 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 ½ to 1½ in., inclusive. They are designated by type denoting chemical composition as follows:TypeDescriptionType 1Medium carbon alloy steelType 2Withdrawn in 2002Type 3Weathering steel
1.4 This specification provides that heavy hex structural bolts shall be furnished unless other dimensional requirements are specified on the purchase order.
1.5 Terms used in this specification are defined in Specification F 1789 unless otherwise defined herein.
1.6 For metric bolts, see Specification A 490M Classes 10.9 and 10.9.3
1.7 The following safety hazards caveat pertains only to the Test Methods portion, Section 1412 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.
