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 Medium-Strength Steel Coupling Nuts—Class 8
Often referred to as extension nuts, use these to connect and extend threaded rods. They're comparable in strength to Class 8.8 bolts.
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.
Steel nuts are best for dry environments, since moisture will cause them to rust. They are ready for painting or welding.
Zinc-plated steel nuts are corrosion resistant in wet environments.
