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

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

Includes inch thread sizes. These Grade 8 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

Closely spaced metric threads prevent loosening from vibration. These Class 10 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

Made from medium-strength steel with a nylon insert, these Class 8 metric locknuts are strong enough to use on most machinery and equipment that’s prone to vibration and temperature changes.

Made from low-strength steel, these locknuts should be used for light duty fastening applications, such as securing.access panels.

These locknuts have good chemical resistance.

Choose these locknuts for their adherence to strict military standards for material and construction.

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

One-third the weight of steel, aluminum locknuts resist corrosion in wet environments.

These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low clearance applications or jam one against a hex nut to hold it in place.

Choose these locknuts for their adherence to strict military standards for material and construction.

Grade 5 locknuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut.

Choose these locknuts for their adherence to strict military standards for material and construction.

Comparable in strength to Grade 8 bolts, these locknuts are about three times stronger than low-strength steel extra-wide thin locknuts.

These locknuts have good chemical resistance.

Known for their strength, these locknuts are zinc-plated to resist corrosion in wet environments.

Grade F nuts are comparable in strength to Grade 5 bolts.

Grade G nuts are comparable in strength to Grade 8 bolts.

These 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.
