Designed for compact set-screw fastening, 5/16-18 x 3/8 316 Stainless Steel Cup Point Socket Set Screw combines 316 stainless steel construction with a cup-shaped point for localized contact at the mating surface.

Applications often include washdown equipment, packaging machinery, and automation systems, where stainless material and socket-drive serviceability matter. 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 point geometry gives the installer a defined end form for localized holding contact rather than a general-purpose threaded plug. Cold Headers works with distributors, maintenance teams, and production buyers that need clear size identification for specialty stainless socket products.
