ABSTRACT:
A ratcheting tool having an axial pawl ratcheting mechanism is provided that may be used for a screwdriver or wrench and comprises a first gear including axial gear teeth on a first side providing for ratcheting in a first direction. A second bidirectional gear has axial teeth on both sides. The second gear is mounted to the first side of the first gear so that the first gear axial gear teeth engage the second gear axial gear teeth and provide an axial pawl ratchet assembly. A ratchet head is provided having an opening for receiving the axial pawl ratchet assembly therein in order to transfer torque between the ratchet head and the axial pawl ratchet assembly. An actuator is provided for adjusting the positioning of the axial pawl ratchet assembly between a first position and a second position.
