Cleanable magnetic driver for threaded fasteners

A threaded fastener driving tool comprising:

• a shank having a front end portion and a rear end portion configured to be coupled to a power tool;
• a sleeve coupled to the front end portion of the shank, the sleeve defining an internal bore having a rear portion and a front socket for driving a threaded fastener;
• an inner shaft having a rear portion received in the internal bore and a front portion with a magnet holder received in the socket, the magnet holder having a front magnetic portion and a rear magnetic portion, the shaft being moveable between a rear position in which the front magnetic portion is disposed within the socket, and a front position where the front magnetic portion is exposed from the socket for cleaning;
• and
• an actuator coupled to at least one of the sleeve and the inner shaft to enable manual movement of the inner shaft between the rear position and the front position,
• wherein the rear magnetic portion is magnetically attracted to the sleeve to bias the inner shaft toward the rear position.

A driver for driving a threaded fastener, the driver comprising:

• an outer shaft having a shank and a sleeve, the shank having a front end portion and a rear end portion configured to be coupled to a power tool, and the sleeve coupled to the front end portion of the shank and defining an internal bore having a round rear portion and a front polygonal socket for driving a threaded fastener having a corresponding polygonal outer geometry;
• an inner shaft having a round rear portion received in the internal bore and a front portion with a magnet holder received in the socket, the magnet holder coupled to a single magnet, the single magnet having a front magnetic portion and a rear magnetic portion, the inner shaft being moveable between a rear position in which the front magnetic portion is disposed within the socket, and a front position where the front magnetic portion is exposed from the socket for cleaning;
• and
• an actuator an actuator fixedly coupled to the inner shaft and received in a longitudinal slot in the sleeve so that the actuator is configured to move between a first position in which the inner shaft is in the rear position and a second position in which the inner shaft is in the front position,
• wherein the inner shaft is composed of a non-ferromagnetic material and the sleeve is composed of a ferromagnetic material so that the rear magnetic portion is magnetically attracted to the sleeve to bias the inner shaft toward the rear position, independent of a spring force.
