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

Optisert's unique diamond-shaped wedges underneath the head gives it a superior grip that helps deters spin-out in the base material of the application. The patent-pending closed-end design provides a sealed option that does not compromise the biting effect of the wedges, delivering superior performance to other round-body, closed-end rivet nuts in the market. The seal helps keep out viscous material from entering inside the base material.   

Ideal applications for Optisert include products that that have softer materials like aluminum, composite, fiberglass, 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 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.
