What is a Nutsert®?

December 5, 2019

A “Nutsert®”, a branded name for the generically referred to “rivet nut”, is a tubular shaped metal fastener with internal threads. Branded types of rivets nuts include Nutsert® by Avdel®, Rivnut® by Bollhoff and Rivkle® by Bollhoff. Many manufactures make rivet nuts, some choose to brand their rivet nuts for marketing purposes. Manufactures typically sell their rivet nuts through distribution, distributors such as Rivet Nut USA.

In 2012, the Avdel® Nutsert® product line was acquired by Stanley® Engineered Fastening.

An Avdel® Nutsert® is a one-piece blind fastener that provides a nut plate to attached a secondary material with a threaded bolt and requires no post-install finishing. An added benefit is no damage is done to the parent material once installed (as can be the case with alternative fasteners, such thermal damage caused by weld nuts).

To install, a hand or power tool engages the threads of the threaded insert fastener and exerts a pull, causing the internally threaded shank to compress and expand tightly against the parent material being fastened – commonly called “upsetting the fastener”. The installation occurs “blindly”, meaning no access to the backside of the parent material is required.

When materials such as sheet metal, tubular structures and plastics are too thin to tap (typically less than 1/2 inch thick), a Nutsert® provides a thread for the parent material. Once installed, a Nutsert® offers strong threads to reliably join thin-walled workpieces. This type of fastener is the ideal money saving fastener for OEMs!
