General Rivet Nut Questions

What is a rivet nut used for? What is a fastener?

A rivet nut allows for the installation of a threaded receptacle into a piece of material where only one side is accessible. Starting with a pre-drilled hole, a rivet nut is inserted and with a special tool, the nut is compressed and crimped around the hole, allowing for a strong permanent bond. Once installed, a standard screw can be inserted into the rivet nut to allow for the fastening of additional material.

What is the difference between a rivet nut and a blind rivet nut?

They are one in the same. The “Blind” name comes from the fact that they are installed in applications where only one side of the material is accessible; therefore, the rivet nut is “blind” to the other side of the material.

What is a slotted rivet nut?

A slotted rivet nut (or Plus Type Nut) is a longer fastener with slits down the sides that allow the nut to more easily compress.

What materials are rivet nuts made out of?

The various materials include: Soft Aluminum Alloy, Steel, Stainless Steel, Copper, and Monel.

What are some industries that generally use rivet nuts?

The industries are essentially limitless, but some of the most popular include: Aerospace & Aviation, Automotive, Industrial Type Equipment, and hobbyists.
