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.
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.
Black-oxide 18-8 stainless steel adapters have a black finish that won’t chip or rub off.
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.
