How to Install Jack Nuts？
1. Insert the jack nut into the pre-drilled hole.
2. Thread the installation tool or screw into the jack nut.
3. Tighten the tool to collapse the legs behind the material.
4. The jack nut expands and creates a secure threaded insert.
Jack nuts are ideal for applications where access to the backside is limited, such as sheet metal, plastic, and fiberglass installations.
