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

With diamond-shaped wedges underneath the head that give it a superior grip, manufacturers can rely on the spin-out performance of this innovative fastener. The Closed End Optisert comes with a standard plastisol seal that helps keep viscous material out of the base material. Non-sealed closed-end options are available as well, along with other seals. 

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

The standard Optisert is available in a variety of options, including open-end, closed-end, and in a variety of different finishings, seals or non-sealed. 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.
