Made from Grade 5 steel, these inch-sized 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.

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.

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

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

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

These locknuts have good chemical resistance.

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

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

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

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

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.
