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

These metric nuts resist oil, grease, and solvents (except mineral acids).

Polycarbonate nuts stand up to oil, grease, and detergents.

Glass-filled nylon nuts are stronger than nylon 6/6 nuts. They resist oil, grease, and solvents (except mineral acids).

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.

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.

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 low-strength steel, these locknuts should be used for light duty fastening applications, such as securing.access panels.

More corrosion resistant than 18-8 stainless steel locknuts, these metric locknuts 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.

A conical washer acts as a spring to add tension between the nut and the material surface for easy installation and mild vibration resistance. These metric locknuts have a smooth rim to resist scratching materials when tightened.

These locknuts have good chemical resistance.

Strong enough for use in most machinery and equipment, these medium-strength metric nuts have serrations on the underside of the flange. The serrations prevent the nuts from loosening in applications with mild vibration.

Metric 316 stainless steel is also known as A4 stainless steel. These flange locknuts have excellent resistance to chemicals and salt water.

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.

For light duty applications, choose these metric-sized coupling nuts.

These metric coupling nuts have good chemical resistance.

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

A smooth rounded body provides a finished look.

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

These metric nuts are about half the strength of medium-strength steel cap nuts. Use them in light duty fastening applications, such as securing access panels.

These metric wing nuts provide more leverage for greater torque while tightening than knurled-head thumb nuts.

Made from 316 stainless steel, these metric wing nuts have excellent chemical resistance and can be used in saltwater environments.

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.

Use these thumb nuts in low-clearance applications or jam one against another nut to hold it in place.

Weld these metric nuts to flat and uneven uncoated steel surfaces for a strong permanent hold.

Square weld nuts have more weld points than hex weld nuts for a stronger hold. Use them on flat surfaces.

Projections on the base concentrate the weld and provide room for heat to dissipate.

Weld these nuts to stainless steel surfaces.

Stainless steel adhesive-mount nuts have excellent corrosion resistance in most environments.

About half the strength of medium-strength steel square nuts, use these metric nuts in light duty fastening applications, such as securing access panels.

Press these metric nuts into a drilled or punched hole with an arbor press or similar pressure tool.

A flat hex head sits flush against the material surface for use in low-clearance applications.

These press-fit nuts have a nylon insert that grips threads to resist loosening.

These press-fit nuts are tin plated to resist corrosion from chemicals and salt water.

About twice as strong as aluminum rivet nuts, these steel rivet nuts are zinc plated for mild corrosion resistance.

These aluminum rivet nuts are one-third the weight of steel rivet nuts and have mild corrosion resistance.

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.

Stronger than stainless steel, these nuts are comparable in strength to Grade 9 bolts.

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Stainless steel thumb screws have excellent corrosion resistance in most environments.

Steel inserts have high strength for durability.

The most corrosion resistant tee nut inserts we offer, these inserts stand up to chemicals and salt water.

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

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.

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.

316 stainless steel studs have excellent resistance to chemicals and salt water.

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.
