5/16-18 x 5/16 18-8 Stainless Steel Cup Point Socket Set Screw is an 18-8 Stainless Steel 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 positioning components, hubs, and collars, where the drawing calls for a specific cup point set screw. 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 5/16-18 thread, 5/16 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 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 stainless socket set screws, including uncommon lengths and replacement requirements.
