A driven component is pivotally connected to the drive component and is adapted to receive a tool bit, drill bit, or otherwise provide a nut driver or socket wrench. A locking mechanism is provided for lockingly engaging the driven component to be in co-axial alignment with the drive component. The drive component includes a shaft or a mandrel having a driving shank formed or provided on one end thereof. The driving shank 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 of the driven component.
