“ Setting the standard for sealing nuts”
Seals Liquid Around Threads
At Bearing Surface Vibration-proof sealing of bolt and nut joints – eliminating the need for washers, surface preparation, packing or other measures. Our single piece design provides a more consistent and reliable seal, saves enormous amounts of time, reduces expenses, and contributes to overall performance efficiency. The patented design and tough virgin Zytel® nylon sealing insert is mechanically encapsulated within the nut face providing the convenience of a one-piece fastener.

How it works:
During installation the insert protrusion (1) slips outwardly against the bearing surface. A completed fold effect compresses the insert (2) to seal and lock as metal-to-metal contact is achieved.
Benefits
- Reusable, non-destructive
- Free spin for easy installation
- Special counterbore unnecessary
- Metal to metal contact at bearing surface
- One piece unit prevents assembly errors
- Indefinite shelf life
