4-48 x 3/32 Alloy Steel Cup Point Socket Set Screw is commonly specified where a component must be secured from within a tapped hole rather than with an external screw head.
Typical use cases include shaft collars, hubs, and machine controls, especially where a headless fastener must hold a component without external head clearance. 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 4-48 thread, 3/32 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.
