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 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.

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.

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

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.

These Grade 8 locknuts are about three times stronger than low-strength steel distorted-thread locknuts.

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

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

These coupling nuts have good chemical resistance.

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