5/16-18 x 1 Brass Flat Head Socket Cap Screw provides a brass countersunk socket fastener option for equipment that benefits from reduced fastener projection and clean appearance.

The material is often selected where the assembly requires brass hardware for electrical equipment, controls, instrumentation, or appearance-sensitive components. It may be used in maintenance repairs, replacement assemblies, and specialty sourcing programs when the design already calls for a brass countersunk socket fastener.

This head style differs from button head, low head, and cylindrical socket head screws because the head is designed to nest into a matching countersunk seat. For this 5/16-18 thread and 1 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 industrial distributors, sourcing teams, and maintenance operations identify uncommon lengths and specialty socket products.
