Quickly install threaded rods and studs using a cordless drill, instead of doing it by hand.

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.

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

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.

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.

These metric coupling nuts have good chemical resistance.

These coupling nuts have good chemical resistance.

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

A smooth rounded body provides a finished look.

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