A tool includes an elongated shaft and a socket positioning assembly disposed on the shaft. A rear end portion of the shaft is configured to be mounted for rotation by a hand tool or a power tool. The shaft is configured to support a first socket and a second socket. Each socket is selectively positionable on the shaft in either a use configuration or in a storage configuration. The socket positioning assembly includes a socket support member configured to support the first socket in its use configuration proximate the front end portion of the shaft, and a socket retainer configured to retain at least the second socket in its storage configuration on the shaft. The storage configuration is between the socket retainer and the rear end portion of the shaft. The socket retainer is positioned between the first socket and the second socket.

A tool bit assembly includes a tool bit having a shaft with a first working region disposed at a first end of the shaft and a first reduced diameter portion proximate the working region and disposed between a first shoulder and a second shoulder. A floating sleeve has a rear portion with a pair of opposed window openings, a front portion supporting a magnet, and a pair of balls, with each ball disposed in one of the window openings. The floating sleeve is receivable over the tool bit with the magnet proximate the first working regions and the balls received in the first reduced diameter portion to allow the floating sleeve to move between a first position in which the balls abut the first shoulder and a second position in which the balls abut the second shoulder.

A fastener driving tool includes a shaft with a working region disposed at a first end of the shaft and configured to drive a fastener, a shank portion disposed proximate a second end of the shaft and configured to couple the shaft to a power tool, and a reduced diameter torsion zone disposed between the shank portion and the working region, the torsion zone extending from a first shoulder closer to the working region to a second shoulder closer to the shank portion. A length (L) and a radius (c) of the torsion zone have been optimized so that approximately half of breakages occur in the working region and approximately half of breakages occur in the torsion zone.
