Metric Low-Strength Steel Coupling Nuts
Often referred to as extension nuts, use these to connect and extend threaded rods. They're about half the strength of medium-strength steel coupling nuts for use in light duty fastening applications.
Zinc-plated steel coupling nuts resist corrosion in wet environments.
Black-oxide steel coupling nuts have a dark surface color and are mildly corrosion resistant in dry environments.

Metric High-Strength Steel Coupling Nuts—Class 10
Often referred to as extension nuts, use these to connect and extend threaded rods. Made from Class 10 steel, they're about 25% stronger than medium-strength steel coupling nuts and comparable in strength to Class 10.9 bolts.
Zinc-plated steel nuts are corrosion resistant in wet environments.
