Frequently Asked Questions
How do Jack Nuts work?
As the screw is tightened, the slitted body collapses (or expands) into "spider-like" legs that grip the back of the mounting material.
What materials can I use them in?
They are excellent for materials that are too thin or brittle to tap, such as plastic, soft metals, wood, composite boards, and glass.
Are they removable?
The screw can be removed, but the expanded anchor body typically remains in place and is difficult to remove without damaging the material.
Can I use them in solid concrete?
No, Jack Nuts are designed for use in hollow bases or thin materials where the legs can expand. They will not function correctly in solid concrete or brick.
