About Nuts, Materials, and Finishes

Nylon Hex Nuts

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

Metric Nylon Hex Nuts

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

High-Strength High-Temperature PEEK Hex Nuts

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.

Fiberglass Hex Nuts

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

High-Temperature Chemical-Resistant PTFE Hex Nuts

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.

Impact-Resistant Polycarbonate Hex Nuts

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

Acid-Resistant PVC Hex Nuts

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

Glass-Filled Nylon Hex Nuts

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

Chemical-Resistant Polypropylene Hex Nuts

Polypropylene nuts resist organic solvents and degreasing agents.

Water-Resistant Acetal Hex Nuts

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

High-Strength Chemical-Resistant PVDF Hex Nuts

Stronger than PTFE nuts and resistant to solvents, bases, and acids—including hydrochloric and nitric acid—these PVDF nuts are often used in chemical processing equipment.

Ceramic Hex Nuts

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

Plastic Thin Hex Nuts

Plastic nuts are chemical resistant, nonconductive, and lightweight.

Thread-Forming Flange Locknuts

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

Fiberglass Flange Nuts

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

Plastic Coupling Nuts

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

Plastic Cap Nuts

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

Metric Plastic Cap Nuts

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

Plastic Pipe Fittings for Oil

Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They have high strength and impact resistance.
