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.

Also known as castle nuts, secure these nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance.

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

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

These flange locknuts are comparable in strength to Grade 8 bolts.

About half the strength of medium-strength steel flange nuts, use these nuts in light duty fastening applications, such as securing access panels.

Fiberglass flange nuts are chemical resistant, nonconductive, and lightweight.

These flange nuts have a black-oxide finish for mild corrosion resistance in dry environments.

These cap nuts have good chemical resistance and may be mildly magnetic.

About half the strength of medium-strength steel cap nuts, use them in light duty fastening applications, such as securing access panels.

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