3/8-16 x 1 Brass Button Head Socket Cap Screw helps designers combine a compact rounded head profile with material properties useful for electrical and instrumentation work. The button-head geometry is chosen for reduced head projection and a smooth exposed appearance while keeping the head visible and accessible. Engineers choose brass here for electrical conductivity, non-magnetic behavior, and non-ferrous construction rather than high-strength structural loading.

Appropriate uses include laboratory equipment and commercial fixtures, where non-ferrous construction and a clean exposed head are often preferred over plain steel hardware. It can also fit laboratory equipment and commercial fixtures, where non-ferrous construction and a clean exposed head are often preferred over plain steel hardware. 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 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.
