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.

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.

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 locknuts have good chemical resistance and may be mildly magnetic.

Also known as Keps and K Lock nuts, these locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance.

These locknuts have a curved washer that acts as a spring for easy installation and mild vibration resistance. The smooth rim makes them less likely to scratch materials when tightened than locknuts with a tooth lock washer.

These locknuts have good chemical resistance.

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.

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.

An irregularly shaped thread grips the bolt for a stronger hold than nylon-insert cap locknuts.
