The present invention provides a wrench having a removable key and key adjustment assembly. The key itself includes a nut receiving face having chamfered upper and lower edge regions to one side of the key and a notch intermediate the other side of the key. The key is removably secured to a threaded stem fitted within a longitudinal opening through the wrench head with a screw securing the stem to the key. The screw releases the stem and the key from another with the stem being then removable through the axial opening and the key itself being removable from the wrench head by engaging the notch with the edge of the cavity and clearing the chamfered edges past the cavity wall suh that the key pulls directly out through the cavity.
