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

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

About half the strength of medium-strength steel nuts, these nuts are for light duty fastening applications.

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

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 are about 25% stronger than medium-strength steel thin hex nuts. Available in inch thread sizes.

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

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.

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

These locknuts have good chemical resistance.

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.

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

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

About half the strength of medium-strength steel locknuts, these are for light duty fastening applications, such as securing access panels.

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel flange nuts.

Stainless steel nuts have excellent corrosion resistance in most environments.

These coupling nuts have good chemical resistance.

Stainless steel coupling nuts have excellent corrosion resistance in most environments.

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

Use these nuts with a sleeve and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.
