ABSTRACT:
An adjustable wrench provides a fixed number of positions between fixed and movable torque applying jaws, the positions corresponding to nominal wrench sizes. One scale in English units provides means to position the jaws in a series of positions corresponding to English unit wrenches. A second scale in metric units provides means to position the jaws in a series of positions corresponding to metric wrenches. A pair of operators or discs have a pointer which is used to select the desired wrench size.
