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

Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most 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 metric-sized coupling nuts are Class 10 steel, so they’re about 25% stronger than medium-strength steel coupling nuts.

These metric 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.

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

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

A smooth rounded body provides a finished look.

With a height that is 50% taller than standard hex nuts, these nuts provide a larger gripping area for installation with a wrench.

Choose these standoffs for their adherence to NAS 1831 specifications.

These standoffs are made to NAS specifications.

Protect components from electrical charges.

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.

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

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of 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.
