This specification covers the requirements for austenitic grade stainless steel socket set screws (SSS), sizes M1.6 through M24, having property classes A1-50 and A1-70. The analysis of the screw material shall conform to the chemical composition specified. Socket set screw shall be subjected to torque test, Vickers hardness test, and corrosion resistance test to meet the requirements prescribed.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers the requirements for austenitic grade stainless steel socket-set screws (SSS) sizes 0.060 through 1.000 in. square head set screws (SHSS) sizes 0.190 through 1.500 in., and slotted headless set screws (HSS) 0.060 through 0.750 in., in two conditions, AF and CW.
1.2 Units—The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
—A complete metric companion to Specification F880 has been developed—F880M; therefore, no metric equivalents are shown in this specification.
1.3 The following hazards caveat pertains only to Test Method Section, Section 12 of this specification. This standard does not purport to address (all of) the safety problems 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.
