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

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

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

Titanium locknuts have a high strength-to-weight ratio and are resistant to acids and salt water.

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.

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.

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

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

Stainless steel locknuts have excellent corrosion resistance in most environments.

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

Stainless steel locknuts have excellent corrosion resistance in most environments.

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

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

These flange locknuts have excellent resistance to chemicals and salt water. They have an irregularly shaped thread that grips the bolt for a stronger hold than nylon-insert flange locknuts.

These nylon flange locknuts form threads as they're tightened to resist vibration.

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