(54) Cleanable magnetic driver for threaded fasteners


(57) A driver (510) for driving a threaded fastener includes a shank (514) and a sleeve (516). The shank (514) has a rear portion (14) configured to be coupled to a power tool. The sleeve defines a bore (518) having a round rear portion (519) and a polygonal front socket (522). An inner shaft (524) has a round rear portion received in the bore and a polygonal front portion (520) that matches the polygonal socket and that includes a magnet holder with front and rear magnetic portions (531, 533). An actuator is coupled to the inner shaft (524) to move the inner shaft (524)between a rear position where the front magnetic portion (533) is within the socket (522), and a front position where the front magnetic portion (533) is exposed from the socket (522) for cleaning. The rear magnetic portion (531) magnetically attracts the inner shaft toward a rear end of the internal bore to bias the inner shaft toward the rear position.
