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

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

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

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

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.

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

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

Also kown as heavy hex nuts, these nuts are about 10% wider and taller than standard hex nuts to distribute load over a large area.

These nuts have good chemical resistance.

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.

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.

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

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