12-28 x 3 1/2 Alloy Steel Cup Point Socket Set Screw is an Alloy Steel Cup Point Socket Set Screw used when a headless internal-hex fastener is specified for retaining or positioning a component.
In tooling, fixtures, and adjustment assemblies, this screw is often selected where compact internal-hex access matters during setup. The socket drive helps maintenance and assembly teams install or remove the fastener without needing side clearance around a head.
Selection should account for the mating material, available drive access, and whether localized point contact is acceptable. This 12-28 x 3 1/2 size gives buyers a precise callout for ordering. Always confirm that the cup point contact is acceptable for the mating component and service conditions. Compared with a plain threaded plug, the cup-shaped end gives the installer a defined point style for holding or adjustment work. Cold Headers works with distributors, maintenance teams, and production buyers that need clear size identification for specialty socket products.
