Designed for compact set-screw fastening, 1/2-20 x 3/4 Brass Cup Point Socket Set Screw combines brass construction with a cup-shaped point for localized contact at the mating surface.

Applications often include couplings, pulleys, and sprockets, where localized contact helps position a component on a shaft. 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 before ordering. Confirm that point contact, brass material, and service conditions fit the application. Final material selection should reflect the mechanical, electrical, environmental, and dimensional requirements of the assembly. Buyers should review the shaft or component surface condition, available drive access, electrical requirements, and required holding action before selecting this item. Cold Headers is a useful source when the part number, thread, point style, brass material, or length is difficult to locate through standard catalog channels.
