Blind Rivet Nuts are internally threaded rivets that can be installed into sheet-metal, tubing, extrusions, and plastics. Blind Rivet Nuts provide a reliable system of inserting high quality load bearing threads, available in three different styles.
A rivet nut, also known as a blind nut or nut-sert, is a one-piece internally threaded and counterbored tubular rivet that can be anchored entirely from one side. There are two types: one is designed to form a bulge on the back side of the panel as a screw is tightened in its threads. The other is similarly drawn in using a screw, but is drawn into the sleeve instead of creating a bulge. Rivet Nuts installed from one side only, provide a deep re-usable thread, even in thin materials.
