4-40 x 5/8 Brass Flat Head Socket Cap Screw supports panel and fixture designs that require a brass countersunk screw with top-side hex socket access.
Applications can include decorative hardware, architectural components, and bracket assemblies. The material is often selected where the assembly requires brass hardware for electrical equipment, controls, instrumentation, or appearance-sensitive components.
When the countersink is prepared correctly, the flat head can sit flush with or close to the surrounding surface to reduce snag points and improve clearance. Cold Headers has supplied specialty industrial socket fasteners since 1962 and supports buyers looking for exact brass socket screw sizes. For this 4-40 thread and 5/8 in. length, review the body diameter, head diameter, head height, hex socket size, and key engagement before approving the fastener for a countersunk assembly.
