ASTM A490-12

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 A325 or A490 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:
  TypeDescription  Type 1Medium carbon alloy steel Type 2Withdrawn in 2002 Type 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 Terminology F1789 unless otherwise defined herein.
1.6 For metric bolts, see Specification A490M Classes 10.9 and 10.9.3
1.7 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.8 The following safety hazards caveat pertains only to the Test Methods portion, Section 12 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.
