3/8-16 x 3/4 Brass Button Head Socket Cap Screw is used where reduced head projection and a clean visible appearance are important on brass hardware. This head style is a practical choice where the fastener should remain accessible while presenting a compact rounded profile. Because brass is non-ferrous, it can be useful in selected electrical, instrument, and laboratory applications where magnetic response is undesirable.

Appropriate uses include electronic equipment and display hardware, where a decorative appearance and lower head projection help exposed hardware look intentional. It can also fit electrical assemblies and control panels, where conductivity and non-magnetic construction can be useful around selected hardware and instrumentation layouts. 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 3/4 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.
