Brass Hex Panel Nuts

These panel nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. They can be fastened with a wrench for more torque while tightening than knurled panel nuts. Also known as dress nuts, they're extremely thin for use in tight spaces such as electrical panels.

Thin-Profile Hex Nuts

About half the height of standard-profile nuts, these fit in spaces with low clearance. You can also use them as jam nuts by threading them against another hex nut to hold it in place.

Bronze

Silicon Bronze—More resistant to salt water than brass, these nuts are a good choice for marine environments. They are also stronger than brass and more resistant to abrasion and wear. Choose them for machinery with rotating parts or other applications where nearby components may rub against the nut.

Brass

Brass—Conductive and nonmagnetic, brass nuts are commonly used to secure electrical equipment, such as circuit board assemblies and mounting brackets, inside enclosures. They're also softer than most metals, so they won't damage other fastening components.

Nickel-Plated Brass—The nickel plating offers better corrosion resistance than plain brass to stand up to solvents, salt water, and chemicals. The plating can wear off over time, so these nuts are not recommended for applications that experience a lot of friction or wear.

Conduit Locknuts

Secure threaded conduit fittings to knockouts. These locknuts keep fittings from shifting, so connections stay stable and wiring is protected inside electrical boxes or enclosures.

For Metal and Plastic Fittings

Nickel-Plated Brass—The plating enhances the corrosion resistance of brass, adding a durable protective finish.

Left-Hand-Thread Thin-Profile Hex Nuts

These nuts tighten when turned to the left. Use them with left-hand rods and screws to prevent counterclockwise-moving parts from loosening. About half the height of standard-profile nuts, these fit in spaces with low clearance. You can also use them as jam nuts by threading them against another hex nut to hold it in place.

Thin-Heavy-Profile Hex Nuts

About half the height of standard-profile hex nuts and 10% wider, these fit in spaces with low clearance and handle heavier loads by distributing them over a larger area. You can also use them as jam nuts by threading them against another hex nut to hold it in place.
