1/4-28 X 7/8 SHCS ALLOY ZIN
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.
