Jack Nut

A jack nut is a type of rivet nut that can be installed from one side of a workpiece. It often has a rubber or plastic sleeve that expands when tightened.

A jack nut fixes into thin sheet, board and similar panels where only one side can be reached. It grips the panel as it is tightened and can take a screw or bolt. Match it to the panel thickness and the screw thread.

Jack nuts are often made in steel or stainless steel for the nut body, with a rubber or plastic sleeve. Steel gives strength, while stainless steel resists corrosion.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance to confirm the material and dimensions. On receipt, check the nut for proper expansion, thread condition, and sleeve integrity.
