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.
Choose black-oxide steel adapters to match the aesthetics of your system or for their mild corrosion resistance. The finish won't chip or rub off. They resist rust in indoor and dry environments, but avoid using them in corrosive environments.
Zinc-plated steel adapters are strong and corrosion resistant.
At about a third of the weight of steel adapters, aluminum adapters are the lightest we offer. They resist corrosion in wet environments.
18-8 stainless steel adapters have good corrosion resistance.
316 stainless steel adapters have the best corrosion resistance. They stand up to wet environments, just like 18-8 stainless steel adapters, but unlike 18-8 stainless steel adapters, they resist corrosion caused by salt water and harsh chemicals.

Left-Hand Threaded Low-Strength Steel Coupling Nuts
These coupling nuts tighten when turned to the left. Also known as extension nuts, use them to connect and extend threaded rods. They're made from low-strength steel for use them in light-duty fastening applications. A zinc plating provides corrosion resistance in wet environments.
