For assemblies that call for a 316 stainless set screw by exact size, 1/4-28 x 1/4 316 Stainless Steel Cup Point Socket Set Screw identifies the required material, cup point geometry, thread, and length.
It is commonly used in couplings, knobs, and handles, where the screw must sit inside a tapped part. The internal hex drive allows socket-wrench access from the threaded hole, which is useful when surrounding components leave little room for external wrenching.
Review the 1/4-28 thread, 1/4 in. length, socket size, cup point diameter, mating surface, and exposure before specifying the item. Confirm that point contact, 316 material, and service conditions fit the application. 316 stainless steel is often selected for improved corrosion resistance where moisture, cleaning chemicals, or chloride exposure matter. The recessed end form is often chosen where a witness mark or indentation on the mating surface is acceptable for the holding method. Cold Headers has supplied specialty socket fasteners since 1962 and helps buyers identify difficult 316 stainless set screw configurations.
