ASTM F837-13

Standard Specification for Stainless Steel Socket Head Cap Screws

ABSTRACT
This specification covers stainless steel metric socket head cap screws (SHCS) intended for use in applications requiring general corrosion resistance. Two groups of stainless steel alloys are covered, austenitic Grade A1 and martensitic Grade C1. Four property classes are covered: austenitic A1-50 in an annealed condition; austenitic A1-55 in a cold worked condition; austenitic A1-70 in a cold worked condition, and martensitic C1-110 in a heat treated condition. Materials shall be tested and the individual grades shall conform to forging; threads; heat treatment; chemical composition; mechanical properties such as thread diameter, tensile strength, yield strength, elongation, core hardness (Vickers and Rockwell); and corrosion resistance values. Workmanship, finish, and appearance are also detailed.
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 Three groups of stainless steel alloys are covered, austenitic Group 1 and 2 and martensitic Group 5.  
1.3 Four property conditions are covered: austenitic Alloy Groups 1 and 2 in an annealed condition (AF) at 85 ksi maximum, in two cold worked conditions (CW) at 80 ksi minimum, (CW1) at 102 ksi minimum, and martensitic Alloy Group 5 in a heat treated condition (HT) at 160 ksi minimum.  
1.4 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 The following precautionary caveat pertains only to the test method portion, Section 13, 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.
