Abstract: A multiple-size nut driver comprising a socket portion and a handle connected to the socket portion for rotating the socket portion. The socket portion includes a plurality of concentric hexagonal sockets slidably mounted along a longitudinal axis of the driver. Each of the sockets slide between a forward operative position and a rearward retracted position. The handle includes a socket selector mounted behind the plurality of concentric hexagonal sockets. The socket selector holds a selected socket in the forward operative position while allowing unselected sockets to retract to the rearward retracted position. The selected socket is then placed over a nut, and turns the nut when the socket portion is rotated by the handle. Alternatively, the driver automatically selects the proper socket for a given nut by allowing sockets smaller than the nut to be retracted by the nut while the proper size socket and larger remain extended.
