  • Adjustable closed-end wrench
    Patent number: 7017456
    Abstract: An adjustable closed-end wrench is adapted for rotating a threaded fastener. The wrench has a handle and a wheel housing located at a free end of the handle. An engagement wheel is arranged within the wheel housing, and has an inner periphery and an outer periphery. The inner periphery defines a fastener-receiving opening adapted for receiving the threaded fastener. The engagement wheel is mounted for selective one-way rotational movement relative to the wheel housing such that the fastener is rotatable in a clockwise or counterclockwise direction.
