Standard Specification for Stainless Steel Socket Head Cap Screws
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the chemical and mechanical requirements for stainless steel inch socket head cap screw (SHCS) with specific nominal thread and intended for use in applications requiring general corrosion resistance. Two groups and four property conditions of stainless steel alloys are covered: austenitic Alloy Group 1 in a specific annealed condition and in two cold worked conditions; and martensitic Alloy Group 5 in a heat treated condition. The screws shall be tested in accordance with the specified mechanical testing requirements for the alloy group and condition nominal thread diameter and length, axial strength, screw extension, and hardness. The screws shall also be tested for tensile strength, yield strength, and elongation.
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. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.
