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.

Change thread sizes or types, such as fine to coarse threads, on parts without changing gender.

The through hole allows you to connect float rods to float valves.

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.

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.

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.

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

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

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.

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

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

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

A smooth rounded body provides a finished look.

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

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

Insert these adjustable mounts into tube ends to level your equipment in a single step.
