ABSTRACT:
An open-end wrench for gripping a hardware element such as a hexagonal nut or the hexagonal head of a bolt is disclosed which allows the wrench to be used for rotational driving of the hardware element in either direction without requiring the wrench to be periodically removed, repositioned, and replaced on the hardware element in order to continue rotation of the hardware element in the desired direction. A retaining member having an opposing jaw is mounted onto a handle having a fixed jaw in a manner whereby the retaining member has simultaneous freedom of movement in both a linear direction and in a rotational direction between first and second positions. When the handle of the wrench is turned in one direction, the nut or the head of the bolt will be rotated, while when the handle of the wrench is turned in the opposite direction, the jaws of the wrench will slip over the nut or the head of the bolt in a ratcheting manner. The wrench may be flipped over to drive the nut or the head of the bolt in the opposite direction.
