For assemblies that call for a 316 stainless set screw by exact size, 1/4-20 x 1/2 316 Stainless Steel Cup Point Socket Set Screw identifies the required material, cup point geometry, thread, and length.

In water-treatment equipment, outdoor machinery, and replacement assemblies, this screw is often selected where 316 stainless is specified for more demanding exposure. 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 1/4-20 x 1/2 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 cup point creates rim-focused contact that may help resist relative movement when the screw, mating material, and installation conditions are appropriate. Cold Headers supports exact-size sourcing for 316 stainless socket set screws, including uncommon lengths and replacement requirements.
