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.

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

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

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 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.

50% taller than standard hex nuts, these metric nuts provide a larger gripping area for installation with a wrench.

These metric locknuts have good chemical resistance.

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.

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

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 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.

These thumb nuts have an aluminum insert to withstand more torque than plastic thumb nuts during installation.

These metric thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The flange distributes pressure over a large area to reduce stress on your part.

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

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

About half the strength and two-thirds the height of medium-strength steel square nuts, use these metric nuts in light duty, low-clearance applications.

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.

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

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

About twice as strong as aluminum rivet nuts, these low-profile rivet nuts are cadmium plated for corrosion resistance.

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

With a slim, round profile and a slotted drive, these metric nuts work in tight spots where there's no room for a wrench to turn. Instead, tighten them from the center of the nut with a slotted screwdriver.

These 18-8 stainless steel inserts have excellent resistance to chemicals and may be mildly magnetic.

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.

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

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.
