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.

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.

Commonly used to fasten structural parts and pumps, these nuts are comparable in strength to Grade 8 steel.

Made of stainless steel, these metric nuts have good chemical resistance and may be mildly magnetic. They have a silicone seal that prevents leaks and seals out contaminants.

More corrosion resistant than 18-8 stainless steel nuts, these nuts can be used in saltwater environments. They're considered heavy hex nuts because they are about 10% wider and taller than standard hex nuts and distribute the load over a large area.

More corrosion resistant than 18-8 stainless steel nuts, these nuts have excellent resistance to chemicals and salt water. They're able to maintain their strength in high-pressure and high-temperature environments and are used with ASTM A193 bolts to fasten pressure tanks, valves, and flanges. Considered heavy hex nuts, they are about 10% wider and taller than standard hex nuts and distribute the load over a large area.

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.

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

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.

With threads that tighten to the left and made of 316 stainless steel, these nuts won’t loosen from counterclockwise motion in saltwater and corrosive environments. They’re half the height of standard hex nuts, so they fit where there’s low clearance.

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

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.

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.

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 stainless steel 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.

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

Made from stainless steel, these metric flex-top locknuts resist chemicals and may be mildly magnetic.

Stainless steel locknuts have excellent corrosion resistance in most environments.

Made from 18-8 stainless steel, these flange locknuts have good chemical resistance and may be mildly magnetic

These flange locknuts have excellent resistance to chemicals and salt water.

Made from 18-8 stainless steel, these flange nuts have good chemical resistance.

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

These metric coupling nuts have good chemical resistance.

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

These metric cap nuts have good chemical resistance and may be mildly magnetic.

These metric cap nuts have excellent resistance to chemicals and salt water.

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

These cap nuts offer at least three-times the thread depth of standard cap nuts and are about twice the height.

An irregularly shaped thread grips the bolt for a stronger hold than nylon-insert cap locknuts. Made of 18-8 stainless steel, these cap locknuts have good chemical resistance.

To resist loosening from vibration, these metric locknuts have a nylon patch bonded to their threads that adds friction. They have good chemical resistance and may be mildly magnetic because they’re stainless steel.

With an irregularly shaped thread, these locknuts grip the bolt for a stronger hold than nylon-insert cap nuts and resist loosening from vibration. They’re made from 316 stainless steel, so they have excellent resistance to chemicals and salt water.

A silicone seal prevents leaks and seals contaminants. Also known as acorn nuts, these cap nuts have a smooth rounded head that covers and protects threads while creating a finished appearance.

You can weld these nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

In addition to joining male- and female-threaded parts, these adapters can increase or decrease metric thread sizes and change the thread pitch.

Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

Twist these adapters onto female metric threads to change pitch or switch thread sizes.

Teeth bite into surfaces for easy installation and mild vibration resistance.

Cap nuts cover and protect threads while providing a finished appearance.
