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.

With threads that tighten to the left and made of 316 stainless steel, these nuts won’t loosen from counterclockwise motion in saltwater and corrosive environments. They’re half the height of standard hex nuts, so they fit where there’s low clearance.

Plastic nuts are chemical resistant, nonconductive, and lightweight.

One-third the weight of steel, aluminum nuts resist corrosion in wet environments.

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.

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

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

These locknuts have good chemical resistance.

Stainless steel locknuts have excellent corrosion resistance in most environments.

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.
