When a maintenance list or drawing calls for a brass cup point set screw, 4-40 x 1 1/2 Brass Cup Point Socket Set Screw provides a clear product callout for purchasing and replacement work.
In electrical controls, knobs, and handles, this screw is often selected where brass material and internal-hex access are useful in a compact assembly. 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 4-40 x 1 1/2 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. The cup point creates rim-focused contact that may help resist relative movement when the screw, mating material, and installation conditions are appropriate. Cold Headers supports exact-size sourcing for brass socket set screws, including uncommon lengths and replacement requirements.
