When a drawing or maintenance bill calls for a cup point set screw, 3-48 x 3/8 Alloy Steel Cup Point Socket Set Screw identifies the required Alloy Steel thread and length clearly for purchasing.
It is commonly used in industrial repairs, pulley hubs, and shaft-mounted components, where drive access is available through the threaded part. The internal hex drive allows socket-wrench access from the top of the threaded hole, which is useful when the surrounding assembly leaves little room for external wrenching.
Review the 3-48 thread, 3/8 in. length, hex socket size, and cup point diameter against the mating part before specifying the item. 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.
