2-56 x 5/16 18-8 Stainless Steel Button Head Socket Cap Screw provides a rounded-head socket screw option for equipment that sees moisture, handling, or routine cleaning. The relatively broad head can be helpful on covers, guards, and panels where the fastener remains visible. The internal hex drive supports socket-key installation where external wrenching space is limited.

Typical applications include brackets, fixtures, and precision assemblies, where the broad bearing surface can help seat the head cleanly on light mounting surfaces. It can also serve control enclosures and service panels, where the smooth exposed appearance is useful when hardware remains visible after assembly. The rounded head profile is useful on visible or frequently handled assemblies.

The stainless construction supports high-humidity industrial service, control equipment, and general machinery without overstating the material's corrosion performance. For the 2-56 thread and 5/16 in. length, the reference head diameter is 0.154-0.164 in. and the head height is 0.038-0.046 in.
