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.

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

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.
