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.

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

Comparable in strength to Grade 5 steel and as resistant to chemicals and salt water as 316 stainless steel.

Often used to fasten parts in engines and turbines, these nuts are comparable in strength to Grade 8 steel.

These nuts resist sticking during installation and are comparable in strength to Grade 5 steel.

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 tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. Made of Grade 2 and Class 04 steel, these nuts can be used for fastening panels and other light duty fastening applications.

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.

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

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

Comparable in strength to Class 12.9 bolts.

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

About half the strength of medium-strength steel extra-wide hex nuts, use these nuts for light duty fastening applications, such as securing access panels.

More corrosion resistant than 18-8 stainless steel nuts, these nuts can be used in saltwater environments.

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

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

Also known as small-pattern hex nuts, these are about 20% narrower than standard hex nuts for use in tight spaces where standard hex nuts won't fit.

Taller than standard hex nuts, these metric nuts provide a larger gripping area for installation with a wrench.

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

A nylon insert keeps metric bolt threads from coming loose due to vibration, wear, and temperature swings. About 25% stronger than medium-strength steel locknuts, these nuts are made of high-strength, Class 10 steel.

Made from Grade 5 steel, these inch-sized locknuts are suitable for fastening most machinery and equipment.

Get a grip on metric bolts exposed to vibration, wear, and changes in temperature. These metric locknuts have a nylon insert that holds onto bolts without damaging their threads.

Choose these locknuts for their adherence to strict military standards for material and construction. They’re low-strength steel, so they should be used for fastening panels and other light duty fastening applications.

These metric locknuts have good chemical resistance.

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

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.

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.

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

These metric locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance.

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

These locknuts have a curved washer that acts as a spring for easy installation and mild vibration resistance. The smooth rim makes them less likely to scratch materials when tightened than locknuts with a tooth lock washer.

These metric locknuts have an irregularly shaped thread at the top of the nut that grips the bolt for a stronger hold than nylon-insert locknuts.

About half the strength of medium-strength steel locknuts, these are for light duty fastening applications, such as securing access panels.
