1/4-20 x 2 1/2 Brass Flat Head Socket Cap Screw provides a brass countersunk socket fastener option for equipment that benefits from reduced fastener projection and clean appearance.

Applications can include maintenance repairs, replacement assemblies, and specialty sourcing programs. For sourcing, the important point is matching the brass material callout, thread size, length, countersunk geometry, and socket-drive requirements exactly.

Because the drive is recessed, the screw can support a smooth exposed surface while still allowing socket-tool engagement during service. Cold Headers gives buyers a focused source for specialty socket products when standard catalog listings do not cover the required configuration. For this 1/4-20 thread and 2 1/2 in. length, review the body diameter, head diameter, head height, hex socket size, and key engagement before approving the fastener for a countersunk assembly.
