ASTM A574-04e1

Standard Specification for Alloy Steel Socket-Head Cap Screws

ABSTRACT
This specification2 covers the requirements for quenched and tempered alloy steel hexagon socket-head cap screws. The screws shall be fabricated from steel which has been made by the open-hearth, basic-oxygen, or electric-furnace process. The screws shall be fabricated from alloy steel made to a fine grain practice. The screws shall be alloy steel conforming to the chemical composition specified. There shall be no evidence of carburization or total decarburization on the surfaces of the heat-treated screws when measured. Hardness, tensile strength, yield strength, and elongation shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers the requirements for quenched and tempered alloy steel hexagon socket-head cap screws, 0.060 through 4 in. in diameter where high strength is required.
Note 1—A complete metric companion to Specification A 574 has been developed-A 574M; therefore no metric equivalents are presented in this specification.
1.2 The following hazard caveat pertains only to the test method 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.
