A driving tool assembly includes a drive component (12) adapted to be connected to a power tool or hand tool. A driven component (14) is pivotally connected to the drive component (12) and is adapted to receive a tool bit, drill bit (16), or otherwise provide a nut driver or socket wrench. A locking mechanism (18) is provided for lockingly engaging the driven component (14) to be in co-axial alignment with the drive component (12). The drive component (12) includes a shaft or a mandrel having a driving shank (22) formed or provided on one end thereof. The driving shank (22) has a non-circular cross-section formed or defined by three or more curved and planar sidewalls. The number of sidewalls preferably includes three, four or six sidewalls, for engaging with a non-circular cavity (26) of the driven component (14). |
