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.

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.

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

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

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

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.
