ASTM F912-11(2017) - 1.6.2017
 
1. Scope

1.1 This specification covers the requirements for quenched and tempered alloy steel socket-set screws (SSS) in nominal diameters 0.060 through 2 in. having hardnesses 45 to 53 HRC.

1.2 These set screws are intended for compression applications only and are not customarily subjected to embrittlement tests. For tensile applications, consult with the manufacturer for proper alloy and hardness.

1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

Note 1: A complete metric companion to Specification F912 has been developed—F912M; therefore, no metric equivalents are shown in this Specification.

1.4 The hazard statement pertains only to the test method section, Section 11 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.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
