1/4-20 x 5/8 316 Stainless Steel Cup Point Socket Set Screw is commonly specified where a component must be secured from within a tapped hole rather than with an external screw head.

Applications often include chemical-processing equipment, hubs, and collars, where the drawing calls for a specific 316 cup point set screw. The internal hex recess gives the installer controlled drive engagement while keeping the fastener profile inside the tapped component.

The verified dimensions below help engineering and purchasing teams compare the screw before ordering. Confirm that point contact, 316 material, and service conditions fit the application. Final material selection should reflect chemical exposure, temperature, load, mating material, and service environment. 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.
