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

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.

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

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.

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 stainless steel locknuts have good chemical resistance and may be mildly magnetic.

These locknuts have an irregularly shaped thread at the top of the nut that grips the bolt for a stronger hold than nylon-insert locknuts.

These locknuts have good chemical resistance.

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

Threads at the top of these locknuts expand to grip the bolt on all sides for a stronger hold than distorted thread locknuts.

Made from 18-8 stainless steel, these flex top locknuts have good chemical resistance and may be mildly magnetic.

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

Also known as castle nuts, secure these nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance.

Stainless steel locknuts have excellent corrosion resistance in most environments.

About half the strength of medium-strength steel flange locknuts, these are for light duty fastening applications, such as securing access panels.

These flange locknuts have excellent resistance to chemicals and salt water.

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

The nylon cap covers and grips the threads to resist loosening.
