These 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.

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

Wings provide more leverage for greater torque while tightening than knurled-head thumb nuts.

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

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

These wing nuts have excellent chemical resistance and can be used in saltwater environments.

These nylon 6/6 wing nuts are chemical resistant, nonconductive, and lightweight.

Made from nylon 6/6, these metric wing nuts are chemical resistant, nonconductive, and lightweight.

A nylon insert grips threads to resist loosening.

A smooth base on these metric nuts provides more contact with the mating surface than weld nuts with projections

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

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

A smooth base provides more contact with the mating surface than weld nuts with projections.

Weld these nuts to uncoated steel surfaces.

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

Weld these 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.

Threads float inside the retainer so you can install a bolt at a slight angle to align with off center parts.

These screw-mount nuts are often used to attach glides and levels to wood.

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

Stainless steel nuts have excellent corrosion resistance in most environments.

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

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.

Choose these locknuts to fasten standard metric threads. They’re Class 8 steel, so they can be used in most fastening applications.

Comparable in strength to Grade 9 bolts, these coupling nuts are about 20% stronger than high-strength steel coupling nuts. Available in inch thread sizes.

These 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.

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

A smooth rounded body provides a finished look.

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

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

Use these tube-end weld nuts with left-hand threaded fasteners.

These include a barrel and a screw.

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.

Pair with a barrel you already have or couple with a different barrel to create a custom fastener. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Designed with a shoulder for the strength to handle side and shear loads.

These include a barrel and a screw.

An unthreaded barrel allows quick assembly with a press or a hammer.

Stainless steel binding barrels and screws have excellent corrosion resistance in most environments.

Add length to a binding barrel.

Brass binding barrels and screws are corrosion resistant in wet environments and electrically conductive.

Plastic binding barrels and caps are chemical resistant, nonconductive, and lightweight.

Create strong joints in wood and wood composite.

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

Brass binding barrels and screws are corrosion resistant in wet environments and electrically conductive.

A tamper-resistant Torx driver is required for installation and removal.

Mount components onto food processing lines, walls, and sanitary equipment while leaving space to clean in between.

These standoffs are made to NAS specifications.

Protect components from electrical charges.

A nickel-chrome plating gives these standoffs a mirror-like finish.

Also known as captive standoffs, a recess under the hex clinches the panel for a strong hold that won't push, pull, or twist out. When mounted, the hex sits flush with the surface and the closed end creates a neat, finished appearance.

Once the end is clinched in place, panels with keyholes easily slide on and off these supports.
