ABSTRACT:
A lug wrench having a gear housing with a fixed gear ratio with drive shafts protruding from either side fixedly connected to separate driving gears. The drive shafts have means on the outside ends whereby the handle and the wrench socket can be used interchangeably thereby providing a wrench with the torquing movement in one position and a speeding movement in the opposite position. The gear housing contains an extension rod at substantially right angles to the drive shafts adapted to brace against stationary surface preventing rotation of the gear box as the wrench handle is being turned.
