Gibraltar 75283291 Jig Foot 5/16-18 Thread Black Oxide

Product Description

The GIBRALTAR 75283291 is a jig foot designed for use in workholding, fixture building, and tooling setups where a stable, adjustable support point is required. Built from low carbon steel with a black oxide finish, this jig foot provides corrosion resistance and a durable surface for repeated use in shop and production environments. It features a 5/16-18 threaded shank, an outer diameter of 7/8 inches, and stands 1 inch in height. A cap screw is included. Machinists, toolmakers, and fixture builders install these as leveling or support feet on jigs, fixtures, and workholding assemblies.

This jig foot is suited for use in machine shops, production facilities, and toolroom environments where precision fixtures and jigs require reliable, repeatable support points. It threads directly into tapped holes in fixture plates, jig bodies, or base components. The black oxide finish reduces light reflection and provides mild corrosion resistance in dry indoor environments. The included cap screw simplifies installation without requiring additional hardware sourcing.
