A wrench includes at least one working end being configured as a circumferentially continuous box and a stop plate configured to be locatable in a working position external from and adjacent to the circumferentially continuous box. The stop plate may include opposed first and second ends, where the first end may be configured to operably engage a shank and the second end may be configured as a plate. The plate may be sized to substantially conform with the circumferentially continuous box and define an opening substantially concentric with the circumferentially continuous box when the stop plate is in the working position.
