Gibraltar 75283390 Jig Foot 1/2-13 Thread Black Oxide

Product Description

The GIBRALTAR 75283390 is a jig foot designed for use in fixturing, tooling, and workholding applications. It features a 1/2-13 thread size and stands 2.25 inches high with an outer diameter of 1.625 inches. Constructed from low carbon steel with a black oxide finish, this jig foot provides a stable, adjustable support point for jigs, fixtures, and similar precision setups. A cap screw is included. The black oxide coating offers mild corrosion resistance and a clean, professional appearance. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This jig foot is suited for machine shop and manufacturing environments where repeatable part positioning is required. It is commonly installed as a leveling or support foot on welding fixtures, inspection fixtures, assembly jigs, and fabrication tooling. The 1/2-13 thread provides broad compatibility with standard tapped mounting holes found in tooling plates and fixture bodies. The included cap screw simplifies installation and reduces the need for additional hardware.
