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 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.

Strong enough for use with most machinery and equipment, these Class 8 metric locknuts have an irregularly shaped thread in the middle of the nut that grips bolts tighter than nylon-insert locknuts.

These locknuts, also known as Fuji locknuts, maintain their holding power with reuse longer than nylon-insert locknuts. They have a spring ring that creates tension as you tighten the nut, keeping them in place.

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

Also known as collar nuts, these metric nuts have a flange that distributes pressure across the surface, so you don't need a washer. Made of high-strength Class 10 steel, they’re about 25% stronger than medium-strength steel flange nuts.

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.

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

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

These metric coupling nuts have good chemical resistance.

Brass coupling nuts are corrosion resistant in wet environments and electrically conductive.

Plastic coupling nuts are chemical resistant, nonconductive, and lightweight.

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

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.

Use these metric nuts in channels and tight spaces where round-base weld nuts won't fit.

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.

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.

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.

Once installed these rivet nuts have a large back flange that distributes the load across a broad area for a strong hold in plastic and composites.

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

These metric nuts have a barrel with multiple threads for secure thread engagement. Also known as U-style clip-on nuts.

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.

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.

Connect male- and female-threaded parts of different thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through.

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.
