1/4-28 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 tooling, fixtures, and adjustment assemblies, where compact internal-hex access is useful during setup. 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 1/4-28 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. This point style is intended for applications where localized contact is part of the retaining method, not for assemblies that require a nonmarking tip. Cold Headers helps match set screw thread, length, point style, material, and socket drive details for industrial purchasing and repair work.
