3-56 x 5/32 18-8 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 positioning components, hubs, and collars, where the drawing calls for a specific 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 to the application before ordering. Confirm that point contact, material, and service conditions fit the application. Final material choice should reflect load, environment, mating material, and maintenance needs. 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 stainless set screw configurations.
