These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion.

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

Tighten these nuts by turning them to the left; once fastened, they resist loosening from counterclockwise motion.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion.

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

These nuts have excellent chemical resistance and can be used in saltwater environments.

Made from nylon 6/6, these nuts resist oil, grease, and solvents (except mineral acids).

These nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.

These nuts are resistant to salt water, electrically conductive, and nonmagnetic.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 5 steel, so you can used these inch-sized nuts for most fastening applications.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 2 steel, so they can be used for fastening panels and other light duty fastening applications

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

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

Made of 316 stainless steel for excellent corrosion resistance—including in salt water—these nuts tighten to the left and won’t loosen from counterclockwise motion. For use in low-clearance areas, they’re half the height of standard hex nuts.

These nuts tighten to the left and won’t loosen from counterclockwise motion.

These nuts have good chemical resistance.

These nuts have good chemical resistance.

Made from Grade 5 steel, these inch-sized locknuts are suitable for fastening most machinery and equipment.

Choose these locknuts for their adherence to strict military standards for material and construction. They’re low-strength steel, so they should be used for fastening panels and other light duty fastening applications.

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

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

These locknuts have good chemical resistance and may be mildly magnetic.

Comparable in strength to Grade 8 bolts, these locknuts are about 25% stronger than medium-strength steel locknuts.

These locknuts have good chemical resistance.

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.

Stainless steel locknuts have excellent corrosion resistance in most environments.

About two-thirds the height of standard steel-insert locknuts, use these locknuts in low-clearance applications or jam one against a hex nut to hold it in place.

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.

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

The nut head rotates while the flange remains stationary to prevent scratching the material surface as you tighten the nut.

These cap nuts have excellent resistance to chemicals and salt water.

Brass cap nuts are corrosion resistant in wet environments and electrically conductive.

Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most applications.

These coupling nuts have good chemical resistance.

Brass coupling nuts are corrosion resistant in wet environments and electrically conductive.

A smooth rounded body provides a finished look.

Use these tube-end weld nuts with left-hand threaded fasteners.

Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.
