    Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.
    Black-Oxide Steel—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—Zinc-plated steel adapters are strong and corrosion resistant.
    Aluminum—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—18-8 stainless steel adapters have good corrosion resistance.
    316 Stainless Steel—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-Thread Coupling Nuts

    Pair with left-hand threaded rods, and turn to the left to tighten. Also known as extension nuts, these are commonly used to connect lengths of threaded rod and join threaded parts.
    Low-Strength Steel
    Image of Product. Front orientation. Contains Annotated, MultipleImages. Coupling Nuts. Left-Hand-Thread Coupling Nuts.
    Rated Grade 2 or lower, these are about half as strong as medium-strength steel coupling nuts. Use them with threaded rods that have a comparable strength rating to avoid stripping threads during installation.
    Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
