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 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 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 corrosion resistant in wet environments, electrically conductive, and nonmagnetic.

These nuts are comparable in strength to Grade 9 bolts.

More corrosion resistant than 18-8 stainless steel nuts, these nuts can be used in saltwater environments.

These locknuts have good chemical resistance.

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

Made from low-strength steel, these locknuts should be used for light duty fastening applications, such as securing.access panels.

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.

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.

These locknuts have an irregularly shaped thread at the top of the nut that grips the bolt for a stronger hold than nylon-insert locknuts.

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

These locknuts have good chemical resistance.

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

Threads at the top of these locknuts expand to grip the bolt on all sides for a stronger hold than distorted thread locknuts.

Known for their strength, these steel locknuts are cadmium plated to resist corrosion in wet environments.

When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut's load to resist spinoff caused by vibration.

About half the strength of medium-strength steel flange 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.

Made from 18-8 stainless steel, these flange nuts have good chemical resistance.

Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most applications.

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.

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

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

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

About half the strength of medium-strength steel cap nuts, use them in light duty fastening applications, such as securing access panels.

Stainless steel nuts have excellent corrosion resistance in most environments.

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

These Grade B7 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.
