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

These nuts are about 20% stronger than high strength steel nuts and are often used in heavy machinery.

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

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.

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

These nuts should be used for light duty fastening applications, such as securing access panels.

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.

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.

Includes inch thread sizes. These Grade 8 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

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

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

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

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

These locknuts have good chemical resistance.

Use these locknuts 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.

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.

Stainless steel locknuts have excellent corrosion resistance in most environments.

About two-thirds the height of standard steel-insert locknuts, use these locknuts in low-clearance applications or jam one against a hex nut to hold it in place.

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.

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

A smooth rounded body provides a finished look.

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.

Stronger than stainless steel, these nuts are comparable in strength to Grade 9 bolts.

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

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

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