ABSTRACT:
A hand ratchet wrench with opposed parallel sides permits utilization of a fixed jaw or adjustable wrench for driving difficult work pieces. In addition, the hand ratchet is provided with a mechanism that permits quick release from socket bits and reversal of the ratcheting mechanism. Finally, an optional hand piece is provided which engages the hand ratchet with detents, to facilitate use of the hand ratchet as a speed wrench.
