Abstract

Double wrench for nuts, especially for automobiles, which is essentially constituted by an elongated metal body, preferably touched with ribs for maximum resistance to torsion and with opposite U-shaped forks at opposite ends thereof. Inside of which are rotating tools to screw and unscrew, determined one by a die or cubic head with four mouths of different diameter, internally toothed in line with four different dimensions of nuts, while the other tool is determined by a tube also having at least one internally serrated mouth, provided for a certain type of automotive nuts, such as those of the spark plugs of the engine, the aforementioned head and said tube being articulated by means of two pairs of axes or lateral stumps that enter crazy in two holes made in the two branches of the "U" mentioned above, appearing between the inner face of the latter and the outer surface of those rotating elements pressure washers that fix by hard friction the position of the same at the time it is necessary to proceed to the threaded or unscrewed, which can be made longitudinally with respect to the axis of the key or with a certain angle, relative to it, depending on the available maneuvering spaces.
