Left-Hand to Right-Hand Female Hex Thread Adapters
Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.
Zinc-plated steel adapters are strong and corrosion resistant.

Low-Strength Steel Coupling Nuts
Also known 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.
