ASTM F837-98

Standard Specification for Stainless Steel Socket Head Cap Screws

SCOPE
1.1 This specification covers the chemical and mechanical requirements for stainless steel inch socket head cap screw (SHCS) with nominal thread 0.060 through 1.500 in. and intended for use in applications requiring general corrosion resistance.
1.2 Two groups of stainless steel alloys are covered, austenitic Group 1 and martensitic Group 5.
1.3 Three property conditions are covered: austenitic Alloy Group 1 in an annealed condition AF at 85 ksi maximum, in a cold worked condition CW at 95 to 70 ksi minimum, and martensitic Alloy Group 5 in a heat treated condition HT at 160 ksi minimum.
1.4 The following precautionary caveat pertains only to the test method portion, Section , 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.
