Gibraltar 75283218 Jig Foot 1/4-20 Thread Black Oxide

Product Description

The GIBRALTAR 75283218 is a jig foot designed for use in fixturing, workholding, and tooling applications where a low-profile, threaded support point is required. Machined from low carbon steel with a black oxide finish, this foot provides a stable, corrosion-resistant contact point for jigs and fixtures on machine tools and assembly setups. The 1/4-20 thread size allows straightforward installation into standard tapped holes. At 0.625 inches outer diameter and 0.625 inches in height, it is compact enough for tight fixture layouts. A cap screw is included. Typical installers are toolmakers, machinists, and fixture builders working in production or maintenance environments.

This jig foot is suited for use in machine shop fixturing, welding jigs, CMM fixtures, and general-purpose workholding setups. It provides a consistent, repeatable contact point on fixture plates, tooling blocks, and fabricated jig bodies. The black oxide finish offers mild corrosion resistance for shop-floor conditions. The compact 0.625-inch height profile keeps fixtures low to the worksurface, which is useful when clearance is limited. The included cap screw simplifies installation and reduces the need to source additional hardware.

Installation Notes

Installation is performed by machinists or toolmakers using standard hand tools. Thread the jig foot into a properly tapped 1/4-20 hole and secure with the included cap screw. Ensure the mating fixture plate or jig body is clean and free of chips or debris before installation. Follow applicable shop safety procedures when working with machine tools or fixturing equipment.
