These screws are chemical and oil resistant, nonconductive, and lightweight. The flange eliminates the need for a washer, distributing pressure where the screw meets the surface.

Fiberglass flange nuts are chemical resistant, nonconductive, and lightweight.

Low moisture absorption and good heat resistance make these washers suitable for wet and harsh environments.

When a metal fastener is tightened onto the washer, the embedded epoxy activates and bonds the underside of the fastener head to the mating surface to prevent loosening. The adhesive fills gaps and spaces that other washers fail to seal.

No need for drilling or welding—these guides mount with adhesive.
