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 bolts.

These metric nuts meet JIS (Japanese industrial Standard) B 1181.

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

PEEK nuts are often used as an alternative to metal hex nuts. They withstand temperatures up to 550° F and resist acids, bases, and salt solutions.

PTFE nuts withstand temperatures up to 500° F. They resist oil, grease, detergents, and most mineral acids. They're the lowest friction plastic nuts we offer, so they thread on smoothly.

Stronger than PTFE nuts and resistant to solvents, bases, and acids—including hydrochloric and nitric acid—these PVDF nuts are often used in chemical processing equipment.

One-third the weight of steel, these metric aluminum nuts are corrosion resistant in wet environments and nonmagnetic.

These nuts should be used for light duty fastening applications, such as securing access panels.

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 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.

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

These metric locknuts have good chemical resistance.

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

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.

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

No need for a washer—these metric medium-strength steel nuts have a flange that distributes pressure across its surface the way a washer does. Made of medium-strength, Class 8 steel, they’re suitable for fastening most machinery and equipment.

Skip the washer—these metric stainless steel nuts have a flange that does the same job, spreading pressure across its surface for a strong hold.

These metric coupling nuts have good chemical resistance.

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

Known for their strength, steel coupling nuts are available with a corrosion-resistant finish.

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

Made from 18-8 stainless steel, these metric nuts have good chemical resistance and may be mildly magnetic.

Made from 18-8 stainless steel, these metric thumb nuts have good chemical resistance and may be mildly magnetic.

These metric thumb nuts have good chemical resistance. The flange distributes pressure over a large area to reduce stress on your part.

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

Two-thirds the height of typical square nuts and made of stainless steel, these metric nuts are designed for use in low-clearance applications in humid, damp, and washdown environments.

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

Stainless steel press-fit nuts have excellent corrosion resistance in most environments.

Also known as broach style captive nuts, these metric nuts have good chemical resistance and may be mildly magnetic.

These tools include everything you need to install press-fit nuts by hand.

The most corrosion resistant low-profile rivet nuts we offer, these stand up to chemicals.

A nonconductive rubber coating insulates the nut from electricity, seals out moisture, and damps vibration.

Stainless steel nuts have excellent corrosion resistance in most environments.

Made from brass, these inserts are nonmagnetic, mildly corrosion resistant, and electrically conductive.

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.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.

Use these rivet nuts for light duty fastening in low-clearance applications. Assortments include rivet nuts, mandrels, and an installation tool.
