ASTM F880M-02(2008)

Standard Specification for Stainless Steel Socket Set Screws (Metric)

ABSTRACT
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.
SCOPE
1.1 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.  
1.2 Units—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 F 880.
1.3 The following hazard caveat pertains only to Section 11, the Test Method Section: This standard does not purport to address 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.
