Class 8 nuts are comparable in strength to Class 8.8 bolts and are suitable for fastening most machinery and equipment.

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

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

About 25% stronger than medium-strength steel nuts, these nuts are comparable in strength to class 10.9 nuts.

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

Tighten these nuts by turning them to the left; once fastened, they resist loosening from counterclockwise motion.

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

These metric nuts are about 20% stronger than high strength steel nuts and are often used in heavy machinery.

These nuts have good chemical resistance and may be mildly magnetic. Metric 18-8 stainless steel is also known as A2 stainless steel.

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

Tighten these nuts by turning them 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.

Hardened for added strength, these nuts are more corrosion resistant to chemicals and salt water than 18-8 stainless steel nuts.

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

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

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 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. They’re Grade 2 steel, so they 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 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.

Comparable in strength to Class 12.9 bolts.

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

These Class 10 nuts are about 25% stronger than medium-strength steel extra-wide hex nuts.

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

These nuts have good chemical resistance.

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.

50% 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.
