Made from Grade 5 steel, these inch-sized nuts are suitable for most 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 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. They’re Grade 2 steel, so they 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.

Bronze nuts are stronger and more resistant to salt water than brass nuts.

These nuts are often used in conjunction with an extra-wide hex nut to fasten Grade 9 bolts in heavy machinery, such as earth-moving equipment.

Stainless steel nuts have excellent corrosion resistance in most environments.

With a shorter hex height than standard DIN 985 locknuts, these nylon-insert locknuts meet international ISO 10511 dimensional standards and are easy to install in tight spaces.

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

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.

Comparable in strength to Grade 8 bolts, these locknuts are about three times stronger than low-strength steel extra-wide thin locknuts.

These locknuts have good chemical resistance.

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

About half the height and 10% wider than standard flex-top locknuts, use these locknuts in low-clearance applications or jam one against an extra-wide hex nut to hold it in place.

These steel panel nuts are zinc plated for corrosion resistance.

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

Use these thumb nuts in low-clearance applications or jam one against another nut to hold it in place.

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

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

These 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.

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

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

These nylon thumb nuts are chemical resistant, nonconductive, and lightweight.

Two-thirds the height of typical square nuts and made of stainless steel, these metric nuts are designed for use in low-clearance applications in humid, damp, and washdown environments.

Combine with mounting blocks to mount and secure threaded-body shock absorbers.

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.

These brass fittings have the strength to handle high-pressure applications.

Use these fittings in extreme-pressure conditions up to 15,000 psi.
