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.

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. Height includes the thickness of the washer. A zinc plating provides corrosion resistance in wet environments.

These locknuts have a curved washer that acts as a spring to add tension between the nut and the material surface 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. Also known as Keps and K-lock nuts.

Black-oxide locknuts are mildly corrosion resistant and have a dark surface color.

Zinc-plated locknuts have an outer layer of zinc that provides corrosion resistance in wet environments.

Threads at the top of these locknuts 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 the threads. These locknuts have equivalent strength to Grade 8 steel locknuts.

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

Choose these locknuts for their adherence to strict military standards for material and construction. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. 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. A silver plating adds lubricity so they thread on smoothly.

Serrations grip the material surface instead of the threads for easy installation and mild vibration resistance. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. About half the strength of medium-strength steel flange locknuts, use them in light duty fastening applications, such as securing access panels. Height includes the flange.

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. A flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. These nuts may be mildly magnetic. Height includes the flange.

A286 stainless steel nuts cannot be reused. Those with lubricant thread onto bolts smoothly.

These nylon flange locknuts form threads as they're tightened to resist vibration. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. They're not reusable. Made from nylon 6/6, they're chemical resistant, nonconductive, and lightweight. Height includes the flange.
