ASTM A574M-12

Standard Specification for Alloy Steel Socket-Head Cap Screws (Metric) (Withdrawn 2015)

ABSTRACT
This specification covers the requirements for quenched and tempered alloy steel socket-head cap screws. The screws shall be fabricated from steel made to fine grain practice and shall be alloy steel conforming to the chemical composition specified. Different tests shall be conducted in order to determine the following mechanical properties of screws: tensile or wedge strength, proof load, yield strength, elongation, Rockwell hardness, and Vickers hardness.
SCOPE
1.1 This specification covers the requirements for quenched and tempered alloy steel hexagon socket-head cap screws, 1.6 mm through 48 mm in diameter having a minimum ultimate tensile strength of 1220 MPa.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
Note 1—This specification is the metric companion of Specification A574.  
1.3 The following hazard caveat pertains only to the test method portions, sections 5.1, 5.6, 8, and 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.
WITHDRAWN RATIONALE
This specification covered the requirements for quenched and tempered alloy steel hexagon socket-head cap screws, 1.6 mm through 48 mm in diameter having a minimum ultimate tensile strength of 1220 MPa.
Formerly under the jurisdiction of Committee F16 on Fasteners, this specification was withdrawn in December 2015. This standard is being withdrawn without replacement due to its limited use by industry.
