1/4-20 x 1/4 Brass Flat Head Socket Cap Screw is a brass flat head socket cap screw for assemblies that use a prepared countersink to reduce surface projection.

The 82-degree flat head is intended for a properly prepared countersunk hole; final seating depends on the mating countersink and the surrounding assembly geometry. Typical uses include electrical enclosures, control panels, and communication equipment, where reduced projection, socket-drive access, and a clean exposed surface can matter.

Brass selection should reflect the mechanical, electrical, environmental, and dimensional requirements of the assembly rather than substitution for steel or stainless hardware. For this 1/4-20 thread and 1/4 in. length, review the body diameter, head diameter, head height, hex socket size, and key engagement before approving the fastener for a countersunk assembly. Cold Headers helps OEM sourcing teams and repair operations locate brass socket fasteners without changing the dimensions specified in the application.
