Jack Nuts
Jack Nuts are used for light duty, thin, or brittle material. They accomodate slightly oversized holes with a large back side footprint similar to a wall anchor.
Jack Nuts utilize a dedicated manual tool for proper installation.
Our jack nut installation tool is designed to effortlessly set jack nuts in sizes ranging from 6-32 – 1/4-20", and M4 – M6. It works by threading the bolt to the jack nut, then dropping the component in the slot of the tool,
inserting it into the pre drilled hole, and squeezing until set. Pressing the release lever, then tightening completes the installation.
