5/16-18 x 1 3/4 Brass Button Head Socket Cap Screw is selected for exposed fastening points where appearance, machinability, and internal hex access matter more than high-strength fastening. 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 architectural hardware and commercial brass components, where the rounded head provides a finished appearance on visible covers and trim. It can also fit maintenance work and assembly operations, where the exact thread and length help match drawings, repair lists, and existing brass hardware. The internal hex drive supports socket-key installation in compact equipment without relying on an external wrenching surface.
For the 5/16-18 thread and 1 3/4 in. length, the reference head diameter is 0.527-0.547 in. and the head height is 0.152-0.166 in. Use the verified dimensions below when checking head projection, socket access, and replacement fit.
Reference dimensions may vary slightly by manufacturer.
