ABSTRACT:
An adjustable wrench has a fixed jaw at its head. A movable jaw is adapted on a slide glidably accommodated in the wrench head, the slide being positionable in optional positions by means of an adjusting screw or other device. The slide has a web in the form of a substantially planar plate running in a slot in the wrench head. A slide rod is in engagement with grooves in the side walls of the slot. The web has an elongate opening and the slide rod constitutes a separate rod, which is inserted in the elongate opening such that it has lateral play.
