Fiberglass Flange Nuts

These fiberglass flange nuts are chemical resistant, nonconductive, and lightweight. They have a flange that distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. Height includes the flange.

Plastic Square Nuts

These fiberglass square nuts are chemical resistant, nonconductive, and lightweight. Large flat sides make them easy to grip with a wrench and keep them from rotating in channels and square holes.

Tee Nut Inserts for Fiberglass

A wide flange distributes the load over a large area. Hammer these inserts into a drilled hole to install. With only three short prongs, they reduce the risk of splitting or cracking fiberglass. They’re zinc-plated steel for mild corrosion resistance.
