Selected for shaft-mounted and adjustment applications, 5-40 x 1/4 Alloy Steel Cup Point Socket Set Screw uses a cup point end form to concentrate contact at the screw tip.
Typical use cases include couplings, knobs, and handles, especially where the installed screw must sit inside the tapped part. 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 5-40 thread, 1/4 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. The recessed end form is often chosen where a witness mark or indentation on the mating surface is acceptable for the holding method. Cold Headers has supplied specialty socket fasteners since 1962 and helps buyers identify difficult set screw configurations.
