    Increase the diameter of your shaft while also making it longer. One side of these adapters clamp onto your shaft; the other side becomes your new larger end so you don’t have to replace the entire shaft. Tighten the clamping screws for a firm, even grip that won’t damage shafts.
    Black-Oxide Steel—Black-oxide steel adapters have a finish that adds a layer of rust resistance but should be used in primarily dry environments. Because they’re steel, they balance high strength and good machinability, making them ideal for general purpose use.
    303 Stainless Steel—303 stainless steel adapters resist corrosion in damp environments. They are easier to machine than other types of stainless steel but more difficult to machine than steel.

    Reduce the diameter of your shaft while adding length. One side of the adapter is a two-piece coupling that clamps onto your existing shaft; a smaller shaft extends from the other side. Tighten the clamping screws for a firm, even grip that won’t damage shafts.

    Adapt your shaft to a threaded end without having to machine threads onto your shaft. These adapters have a threaded end that mounts into tapped holes or can be used for threaded accessories, such as mixer propellers or fan blades. To attach these adapters to your existing shaft, tighten the clamping screws for a firm, even grip that won’t damage shafts. Made of steel, these adapters balance high strength and good machinability, making them ideal for general purpose use. They have a black-oxide finish that resists rust but should be used in primarily dry environments.
