When a maintenance list or drawing calls for a brass cup point set screw, 1/4-20 x 5/16 Brass Cup Point Socket Set Screw provides a clear product callout for purchasing and replacement work.

In couplings, pulleys, and sprockets, this screw is often selected where localized contact helps position a component on a shaft. The socket drive helps maintenance and assembly teams install or remove the fastener without needing side clearance around a head.

Selection should account for mating material, drive access, conductivity requirements, environmental exposure, and whether localized point contact is acceptable. This 1/4-20 x 5/16 size gives buyers a precise callout for ordering. It can fit electrical equipment, controls, instrumentation, fixtures, panels, and light-duty machinery when brass is specified. This point style is intended for applications where localized contact is part of the retaining method, not for assemblies that require a nonmarking tip. Cold Headers helps match set screw thread, length, point style, material, and socket drive details for industrial purchasing and repair work.
