1/4-28 x 5/8 Brass Cup Point Socket Set Screw is a Brass Cup Point Socket Set Screw used when a headless internal-hex fastener is specified for retaining or positioning a component.

It is commonly used in shaft collars, hubs, and control components, where a headless fastener secures a part without external head clearance. 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, 5/8 in. length, socket size, cup point diameter, mating surface, and material requirements before specifying the item. Confirm that point contact, brass material, and service conditions fit the application. Brass is often selected for nonferrous construction, electrical conductivity, general corrosion resistance, and distinctive appearance. 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 brass socket products.
