Selected for shaft-mounted and adjustment applications, 3-48 x 1/8 Alloy Steel Cup Point Socket Set Screw uses a cup point end form to concentrate contact at the screw tip.
Applications often include couplings, knobs, and handles, where the installed screw must sit inside the tapped part. The internal hex recess gives the installer controlled drive engagement while keeping the fastener profile inside the tapped component.
The verified dimensions below help engineering and purchasing teams compare the screw to the application before 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.
