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.

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.

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

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

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

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.

About half the strength of medium-strength steel locknuts, these are 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.

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.

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.

When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut’s load to resist spinoff caused by vibration.

These locknuts are suitable for fastening most machinery and equipment.

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

These nuts are about 25% stronger than medium-strength steel flange locknuts.

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

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