For assemblies that call for a 316 stainless set screw by exact size, 4-40 x 1/4 316 Stainless Steel Cup Point Socket Set Screw identifies the required material, cup point geometry, thread, and length.
In couplings, knobs, and handles, this screw is often selected where the screw must sit inside a tapped part. The socket drive helps maintenance and assembly teams install or remove the fastener without needing side clearance around a head.
Selection should account for mating material, drive access, chloride or chemical exposure, temperature, and whether localized point contact is acceptable. This 4-40 x 1/4 size gives buyers a precise callout for ordering. It can fit washdown equipment, outdoor machinery, instrumentation, water-treatment hardware, and process equipment when 316 is specified. 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.
