For assemblies that call for an exact set screw size, 3/4-16 x 2 1/2 Alloy Steel Cup Point Socket Set Screw provides an Alloy Steel cup point design with internal hex drive access.

It is commonly used in replacement assemblies, hubs, and positioning components, where the drawing calls out an exact cup point set screw size. 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 3/4-16 thread, 2 1/2 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. 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.
