ABSTRACT:
An improved hand tool includes a well at the top of the handle into which the upper end of the shank extends. The well is adapted to receive a torque producing socket wrench drive which engages the shank in order to transmit the torque producing drive directly to the tip of the hand drive tool. In the preferred embodiment the shank which extends into a well has a hexagonal cross-section and is adapted to cooperate with a standard socket wrench. Tips of various configuration may be employed.
