5/16-18 x 1 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 internal hex drive keeps the tool engagement inside the head, which is useful in compact assemblies. 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.
18-8 stainless steel is commonly used in manufacturing equipment, packaging machinery, and maintenance environments where moisture may be present. For the 5/16-18 thread and 1 in. length, the reference head diameter is 0.527-0.547 in. and the head height is 0.152-0.166 in.
Reference dimensions may vary slightly by manufacturer.
