Selected for shaft-mounted and adjustment applications, 4-40 x 1 1/2 Alloy Steel Cup Point Socket Set Screw uses a cup point end form to concentrate contact at the screw tip.
Typical use cases include replacement assemblies, hubs, and positioning components, especially where the drawing calls out an exact cup point set screw size. The internal hex drive keeps installation access compact while the headless body remains contained within the mating part.
For purchasing and replacement work, confirm the 4-40 thread, 1 1/2 in. length, socket size, and cup point diameter match the drawing or installed part. 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.
