About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.

The left-hand threads on these coupling nuts resists loosening from counterclockwise vibration. Use in light duty applications.

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

These metric-sized coupling nuts are Class 10 steel, so they’re about 25% stronger than medium-strength steel coupling nuts.

These coupling nuts have good chemical resistance.

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

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

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

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

Create strong joints in round tubes.

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.

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.

Join threads with small diameters to large or course threads to fine with these inch-sized adapters.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

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

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.

Join two female-threaded parts of various thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through.

These standoffs are made to NAS specifications.

Protect components from electrical charges.

These standoffs are designed to fit in the limited space of compact electronics such as laptops and hand-held devices.

Use these nuts with compression sleeves and fittings to create a strong seal on stainless steel tubing.

Tighten these nuts onto high-pressure compression sleeves and fittings to create a strong seal on stainless steel tubing.

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

Pair these nuts with compression sleeves and high-pressure fittings. They withstand about twice as much pressure as nuts for standard compression fittings, so they’re good for hydraulic power applications.

Use these nuts with plastic compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation.

Use these nuts with high-temperature compression fittings for food and beverage to create a seal on plastic tubing.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.
