Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels.

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. Made of Grade 2 steel, these nuts can be used for fastening panels and other light duty fastening applications.

Useful in low-clearance applications, these metric nuts are roughly half the height of standard hex nuts, but aren’t as strong. All are 18-8 stainless steel, which is nearly as strong as steel but won’t rust in outdoor, washdown, and other corrosive environments.

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

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

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 brass, these metric nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. About half the height of standard hex nuts, they are useful in low-clearance applications but have less tensile strength.

Plastic nuts are chemical resistant, nonconductive, and lightweight.

One-third the weight of steel, aluminum nuts resist corrosion in wet environments.

Use these nuts for light duty fastening applications, such as securing access panels.

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

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 25% stronger than medium-strength steel thin locknuts.

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

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

Use these locknuts for light duty fastening applications, such as securing access panels.

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

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.

All of these stainless steel panel nuts have some chemical resistance.

These panel nuts are knurled to provide a secure grip for tightening and loosening by hand.

These nuts have a black-oxide finish for mild corrosion resistance in dry environments.

These thumb nuts have good chemical resistance. The flange distributes pressure over a large area to reduce stress on your part.

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

These metric thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The flange distributes pressure over a large area to reduce stress on your part.

Made from 18-8 stainless steel, these metric thumb nuts have good chemical resistance and may be mildly magnetic.

These thumb nuts have an aluminum insert to withstand more torque than plastic thumb nuts during installation.

Tighten these thumb nuts with a wrench for more torque while fastening.

Made of Class 04 steel and about two-thirds the height of standard steel square nuts, these nuts are suitable for most low-clearance fastening applications.

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.

Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle.

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

The strongest steel fittings we offer, these can withstand extreme-pressure applications.
