8-32 x 3/8 Brass Button Head Socket Cap Screw provides a brass socket-drive option for assemblies that need a broad bearing surface and a smoother head profile. Compared with taller head styles, the rounded button head can reduce snag potential on panels, covers, and handled surfaces. The material is often selected when conductivity, machinability, and appearance are more relevant than the strength profile of alloy steel.

Appropriate uses include machine covers and automation equipment, where internal hex drive access supports installation where side clearance for external tooling is limited. It can also fit instrumentation and precision equipment, where the finished button head keeps visible fastening points smooth while the material machines cleanly. The internal hex drive supports socket-key installation in compact equipment without relying on an external wrenching surface.

For the 8-32 thread and 3/8 in. length, the reference head diameter is 0.298-0.312 in. and the head height is 0.077-0.087 in. Use the verified dimensions below when checking head projection, socket access, and replacement fit.
