A combination marking tool and wrench which comprises a triangular speed square having a T-bar extending substantially along the length of an outer edge of one of the sides of the triangular speed square. The T-bar has at least one nut engaging shaped opening located on its face and projecting outwardly away from the T square and near an end of said bar. Also shown is a speed square which contains additional marking scales and speed squares which are brightly marked so as to be easily found as well as speed squares easily identifiable via alphanumeric identification codes. More useful marking scales, including metric, and the rearrangement thereof provide greater speed, accuracy, convenience and utility for the speed square. |
