Sherex's Optisert is the best performing round body rivet nut on the market today. 

Optisert's unique diamond-shaped wedges underneath the head give it a superior grip that helps deters spin-out in the base material of the application.  

Ideal applications for Optisert include products that have softer materials like aluminum, composite, fiberglass, plastic. This new round body fastener is already being used in the automotive, EV, and heavy truck industries.

The standard Optisert is available in a variety of options, including open-end, closed-end sealed, and in a variety of different finishings and optional seals. Please download our 3D models and if you have any questions, please contact us!

Please note: Grip range can be affected by parent material and hole size. Sherex recommends trial installations to determine the proper grip range for the application. Contact Sherex for details.
