When a drawing or maintenance bill calls for a cup point set screw, 12-28 x 1/8 Alloy Steel Cup Point Socket Set Screw identifies the required Alloy Steel thread and length clearly for purchasing.
In gears, pulleys, and sprockets, this screw is often selected where point 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 the mating material, available drive access, and whether localized point contact is acceptable. This 12-28 x 1/8 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.
