Over 48,000 metals now include traceable material certificates.

Includes inch thread sizes. These Grade 8 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

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

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

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.

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

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

These locknuts have good chemical resistance.

These locknuts have good chemical resistance.

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.

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 locknuts have good chemical resistance.

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

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.

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

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

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

These flange locknuts have serrations that grip the material surface instead of the threads for easy installation and mild vibration resistance.

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.

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

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