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

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.

These coupling nuts have good chemical resistance.

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

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

A smooth rounded body provides a finished look.

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

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.

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.

Protect components from electrical charges.

These hangers have internal threads for use with threaded rods, bolts, and anchors.
