For assemblies that call for a stainless set screw by exact size, 5/16-18 x 7/16 18-8 Stainless Steel Cup Point Socket Set Screw identifies the required 18-8 material, cup point geometry, thread, and length.
In fixtures, production equipment, and retention work, this screw is often selected where localized holding contact is acceptable for the mating surface. The socket drive helps maintenance and assembly teams install or remove the fastener without needing side clearance around a head.
Selection should account for the mating material, available drive access, environmental exposure, and whether localized point contact is acceptable. This 5/16-18 x 7/16 size gives buyers a precise callout for ordering. It fits many indoor industrial, outdoor general-service, instrumentation, and routine-cleaning applications. 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.
