ABSTRACT:
An adjustable wrench in which a slidable jaw is snapped toward a fixed jaw in an almost fully closed position by the force of a helical spring. The slidable jaw is not fully snapped closed to enable a close tolerance adjustment to be easily made for spacing requirements. The clutch teeth on the slidable jaw are locked in various equally spaced positions by counter acting locking teeth on an adjacent movable plate. The plate is held against the slidable jaw by a second helical spring located in the handle of the adjustable wrench.
