ASTM F912M-04e1 - 1.8.2004
 
1. Scope

1.1 This specification covers the requirements for quenched and tempered alloy steel socket set screws (SSS) M1.6 through M24 sizes having hardnesses 45 to 53 HRC, ISO 898/5 property class 45H.

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 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.

Note 1—This specification is the metric companion of Specification F 912.
