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

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.

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

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

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.

Plastic nuts are chemical resistant, nonconductive, and lightweight.

A nylon insert keeps metric bolt threads from coming loose due to vibration, wear, and temperature swings. About 25% stronger than medium-strength steel locknuts, these nuts are made of high-strength, Class 10 steel.

Made from Grade 5 steel, these locknuts are suitable for fastening most machinery and equipment.

Get a grip on metric bolts exposed to vibration, wear, and changes in temperature. These metric locknuts have a nylon insert that holds onto bolts without damaging their threads.

Choose these locknuts for their adherence to strict military standards for material and construction. They’re low-strength steel, so they should be used for fastening panels and other light duty fastening applications.

These metric locknuts have good chemical resistance.

More corrosion resistant than 18-8 stainless steel locknuts, these locknuts have excellent resistance to chemicals and salt water.

Brass locknuts are corrosion resistant in wet environments and electrically conductive.

Titanium locknuts have a high strength-to-weight ratio and are resistant to acids and salt water.

With a shorter hex height than standard DIN 985 locknuts, these nylon-insert locknuts meet international ISO 10511 dimensional standards and are easy to install in tight spaces.

These Grade 8 locknuts are about 25% stronger than medium-strength steel thin locknuts.

These locknuts have good chemical resistance and may be mildly magnetic.

More corrosion resistant than 18-8 stainless steel locknuts, these have excellent resistance to chemicals and salt water.

Use these locknuts for light duty fastening applications, such as securing access panels.

More corrosion resistant than 18-8 stainless steel locknuts, these have excellent resistance to chemicals and salt water.

These locknuts have good chemical resistance.

Made from Grade 8 steel, these locknuts are about 25% stronger than the same locknut made with medium-strength steel.

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

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

A nylon insert on these metric nuts prevents vibration from loosening them, and a domed head protects the threads at the end of the bolt from damage and debris.
