Drill holes close together. These bushings have a thinner wall than typical bushings to fit side by side in a fixture plate. Also known as jig bushings, they precisely guide bits and other cutting tools to ensure holes and cuts are consistent from part to part. You can also use them as spacers, shims, and machinery bushings. Made of hardened, ground steel, they resist wear and last for many cycles without needing to be replaced. Since their wall is so thin, these bushings may be slightly oval when you receive them but will conform to the shape of your hole.

Press into place with a manual or hydraulic press. Since these bushings are sized slightly larger than the hole for an extremely tight fit, they’ll stay put permanently. These are ANSI Type P bushings—also known as headless bushings—which means you don’t need to counterbore the hole to mount them flush.
