• Optisert -- Closed End | Steel
Sherex's Closed End Sealed Optisert is the best option for a closed end, round body rivet nut. 

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 dust and viscous material from entering inside the base material. 

Optisert is available in a variety of different finishings, seals or no seal. 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.
