8-32 X 3/8 SHCS ALLOY
Description
An externally threaded fastener with unified threads, a cylindrical head with a flat chamfered top surface, knurled cylindrical sides, and hexagonal recess, made from alloy steel.
Application/Advantages
Ideal for precision assembly work with close tolerances and applications needing a well-tooled appearance. Supplies greater tensile strength than equivalent sizes of Grade-5 or Grade-8 hex head cap screws while requiring less surface area or counterbore since the fastener is internally wrenched.
Heat Treatment
Cap screws shall be heat treated by oil quenching from above the transformation temperature and then tempered by reheating to at least 700°F to achieve mechanical properties as defined in ASTM A574.
