Made from nylon 6/6, these nuts resist oil, grease, and solvents (except mineral acids).

These metric nuts resist oil, grease, and solvents (except mineral acids).

Fiberglass nuts are stronger than nylon 6/6 nuts. They resist acids, solvents, salt water, and oil.

PEEK nuts are often used as an alternative to metal hex nuts. They withstand temperatures up to 550° F and resist acids, bases, and salt solutions.

PTFE nuts withstand temperatures up to 500° F. They resist oil, grease, detergents, and most mineral acids. They're the lowest friction plastic nuts we offer, so they thread on smoothly.

Glass-filled nylon nuts are stronger than nylon 6/6 nuts. They resist oil, grease, and solvents (except mineral acids).

Polycarbonate nuts stand up to oil, grease, and detergents.

For use in wet environments, acetal nuts resist alcohol, gasoline, and solvents.

Polypropylene nuts resist organic solvents and degreasing agents.

PVC nuts resist acids, alkalies, salt solutions, and alcohol.

Ceramic nuts won't melt, seize, or become brittle—even at temperatures up to 3000° F.

Plastic nuts are chemical resistant, nonconductive, and lightweight.

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

These untapped nylon flange locknuts form threads as they're tightened to resist vibration.

These nylon 6/6 cap nuts are chemical resistant, nonconductive, and lightweight.

These metric nylon 6/6 cap nuts are chemical resistant, nonconductive, and lightweight.

Plastic coupling nuts are chemical resistant, nonconductive, and lightweight.
