The 1/2″ Threaded Steel (Black Oxide) Shaft Adapter is designed to connect a smooth shaft to a threaded bore while modifying, extending, or repairing an existing shaft without requiring complete shaft replacement. Precision-machined from black oxide steel, it features a fully machineable output shaft that can be customized to suit specific size or configuration requirements. The clamp-type coupling end provides high clamping force with a secure, non-marring grip, while eliminating the need for welding.
