ASTM A574-00

Standard Specification for Alloy Steel Socket-Head Cap Screws

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 A574 has been developed-A574M; 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.
