3/8-16 x 1/2 Brass Button Head Socket Cap Screw is specified where engineers want a smooth exposed head, socket-drive access, and the electrical advantages of non-ferrous construction. The internal hex drive keeps the installation tool inside the head, which is useful when external wrench clearance is limited. Brass is appropriate for many low-load mechanical assemblies where corrosion resistance in general service, appearance, and electrical behavior matter.

Appropriate uses include electrical assemblies and control panels, where conductivity and non-magnetic construction can be useful around selected hardware and instrumentation layouts. It can also fit electronic equipment and display hardware, where a decorative appearance and lower head projection help exposed hardware look intentional. The internal hex drive supports socket-key installation in compact equipment without relying on an external wrenching surface.

For the 3/8-16 thread and 1/2 in. length, the reference head diameter is 0.636-0.656 in. and the head height is 0.185-0.199 in. Use the verified dimensions below when checking head projection, socket access, and replacement fit.
