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

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

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

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

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

Comparable in strength to Grade 8 bolts, these locknuts are about 25% stronger than medium-strength steel locknuts.

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

These Grade 8 locknuts are about three times stronger than low-strength steel distorted-thread locknuts.

These locknuts have good chemical resistance.

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

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 include a two-piece clamp that expands to grip the bolt on all sides and a concave jam nut that clamps the threads onto the bolt for added vibration resistance. They're also known as drake-style nuts.

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.

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