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 should be used for light duty fastening applications, such as securing access panels.

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.

Bronze nuts are stronger and more resistant to salt water than brass nuts.

Titanium nuts have a high strength-to-weight ratio and are resistant to acids and salt water.

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

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

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

Grade 5 locknuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut.

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

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.

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

These thumb nuts have good chemical resistance. The flange distributes pressure over a large area to reduce stress on your part.

These thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The flange distributes pressure over a large area to reduce stress on your part.

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

These nylon thumb nuts are chemical resistant, nonconductive, and lightweight.
