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. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.

Zinc-plated steel locknuts resist corrosion in wet environments.

Black ultra-corrosion-resistant coated steel nuts are more corrosion resistant than zinc-plated nuts in wet environments. They're also known as black luster locknuts.

Choose these locknuts for their adherence to strict military standards for material and construction. 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. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. A cadmium yellow-chromate plating provides corrosion resistance in wet environments and adds lubricity so they thread on smoothly.

About two-thirds the height of standard flex-top locknuts, use these in low-clearance applications or jam one against a hex nut to hold it in place. Threads at the top of the nut expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads. These locknuts have equivalent strength to Grade 8 steel locknuts.

Plain steel locknuts are uncoated and ready for painting.

Cadmium-plated locknuts are corrosion resistant in wet environments. The plating adds lubricity so they thread on smoothly.

These 18-8 stainless steel locknuts have good chemical resistance and may be mildly magnetic. They're about two-thirds the height of standard flex-top locknuts. Use them in low-clearance applications or jam one against a hex nut to hold it in place. Threads at the top of the nut expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads.

These thumb nuts have good chemical resistance and may be mildly magnetic. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment.

Passivated stainless steel nuts provide added protection against oxidation and corrosion.

These thumb nuts have excellent chemical resistance and can be used in saltwater environments. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment. They may be mildly magnetic.

These thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment.

Zinc-plated brass nuts are more corrosion resistant than plain brass nuts.
