1/4-20 x 1 3/4 Brass Button Head Socket Cap Screw is used where reduced head projection and a clean visible appearance are important on brass hardware. The broader bearing surface can be helpful on covers, light brackets, and equipment panels where the head remains visible. The material supports clean machining and a finished look for commercial hardware, instruments, and visible assemblies.

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 1/4-20 thread and 1 3/4 in. length, the reference head diameter is 0.419-0.437 in. and the head height is 0.122-0.132 in. Use the verified dimensions below when checking head projection, socket access, and replacement fit.
