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

These nuts are half the height of standard hex nuts, and have closely spaced threads to prevent loosening from vibration. Half as strong as medium-strength steel nuts, they are often used for light-duty applications, such as fastening signs in place.

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

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.

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

These metric nuts are made of 316 stainless steel and half as tall as regular hex nuts—use them around chemicals and salt water when space is limited.

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.

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

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.

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

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

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.
