ASTM F837-08

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.
