Abstract: A ratcheting adjustable wrench is disclosed. The wrench has a main body defining a wrench head, handle and fixed jaw. The main body is fabricated of hardened sheet metal formed from laminations. The adjustable wrench has a pin/slot guide mechanism to retain and provide position adjustment for an adjustable jaw. A locking mechanism allows the adjustable jaw to ratchet over the corners of a fastener being tightened. In a locked position, the wrench operates like a standard adjustable wrench. Moving a trigger to an unlocked position allows the worm gear mechanism to shift axially for additional travel. The movable jaw engaged to the worm gear is thereby also allowed to shift position so that the adjustable jaw wrench can rotate over the points of the fastener being torqued.
