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

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 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.

Made from Grade 2 steel, 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 have good chemical resistance and may be mildly magnetic.

Made with fine-pitch threads, vibration is less likely to loosen these metric nuts than those with coarse-pitch threads since the threads sit closer together. Also called jam nuts, they are roughly half the height of standard hex nuts, so they’re good for applications with low clearance.

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.

These nuts are corrosion resistant in wet environments,electrically conductive, and nonmagnetic.

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.

Titanium nuts have a high strength-to-weight ratio and are resistant to acids and salt water.

Plastic nuts are chemical resistant, nonconductive, and lightweight.

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

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

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

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.

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

Stainless steel nuts have excellent corrosion resistance in most environments.

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

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

These steel panel nuts are zinc plated for corrosion resistance.

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

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

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

These locknuts have good chemical resistance.

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

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

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

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.

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.

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

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.

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