A ratcheting adjustable wrench (100) is disclosed. The wrench (100) has a main body defining a wrench head (102), handle (104)and fixed jaw (106). The main body is fabricated of hardened sheet metal formed from laminations. The adjustable wrench (100) has a pin/slot guide mechanism to retain and provide position adjustment for an adjustable jaw (140). A locking mechanism (200) allows the adjustable jaw (140) to ratchet over the corners of a fastener being tightened. In a locked position, the wrench (100) operates like a standard adjustable wrench. Moving a trigger (210) to an unlocked position allow the worm gear mechanism (170) to shift axially for additional travel. The movable jaw (142) engaged to the worm gear (170) is thereby also allowed to shift position so that the adjustable jaw wrench (100) can rotate over the points of the fastener being torqued.
