These locknuts include a flex-top locknut that expands to grip the bolt on all sides and a concave jam nut that clamps the threads onto the bolt for added vibration resistance. They're also known as drake-style nuts.

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.

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.

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

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.

Stainless steel locknuts have excellent corrosion resistance in most environments.

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.

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

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 locknuts have good chemical resistance and may be mildly magnetic.

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

These locknuts have good chemical resistance.

Grade 5 locknuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut.

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

Attach these slip-on nuts at any point on a threaded rod for quick installation.

Attach these metric slip-on nuts at any point on a threaded rod for quick installation.

Stainless steel nuts have excellent corrosion resistance in most environments.

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.

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.

Made from Grade 2 steel, these nuts should be used for light duty fastening 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 2 steel, so they can be used for fastening panels and other light duty fastening applications

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 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 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.

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

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

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.

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