1/4-20 x 1 1/2 Brass Flat Head Socket Cap Screw gives engineers a brass internal-hex fastener for countersunk holes where a smooth exposed face is part of the design.

Applications can include instrumentation, laboratory fixtures, and display hardware. Engineers may choose brass for control hardware, decorative assemblies, instrumentation, and replacement work where conductivity and appearance are relevant.

The internal hex drive supports installation from above the workpiece, which is useful in compact layouts where side wrench clearance is limited. Cold Headers provides purchasing support for hard-to-find socket screws and exact-size replacement hardware used in industrial assemblies. For this 1/4-20 thread and 1 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.
