ABSTRACT:
An articulated wrench includes an elongate handle with a generally U-shaped depression at an end of the handle with an edge portion of the handle extending on either side of the depression, and a wrench head formed as a generally planar body with an aperture therein for engaging a fastener to be turned with the wrench, with the body of the wrench head nested into the depression in the handle with the edge portions of the handle on either side of the depression extending along a portion of the edge of the wrench head, and with the wrench head pivotally interconnected to the handle so as to allow rotation of the wrench head relative to the handle. The proportions of the wrench head are selected and the connection between wrench head and handle are selected so as to minimize the clearance required between a fastener and adjacent obstructions in a confined space for engagement of the fastener with the wrench.
