For assemblies that call for a stainless set screw by exact size, 5-40 x 7/16 18-8 Stainless Steel Cup Point Socket Set Screw identifies the required 18-8 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 top of the threaded hole, which is useful when surrounding components leave little room for external wrenching.
Review the 5-40 thread, 7/16 in. length, hex socket size, cup point diameter, and mating surface before specifying the item. Confirm that point contact, material, and service conditions fit the application. 18-8 stainless is selected for general corrosion resistance, clean appearance, and ordinary moisture exposure. 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 socket products.
