Abstract: A crosswise wrench includes a prismatic core with a polygonal cross-section, a face plate nut head on one end and a working point on the other end. The wrench also includes three circular grooves and an extended element having face plate nut heads on its ends. The extended element has at least three identical pairs of apertures with mutually perpendicular axes crossing a longitudinal axis of the extended element at a right angle.

Abstract: The invention relates to mechanical engineering. The crosswise wrench comprises a prismatic core with a polygonal cross-section, a face plate nut head on the one end and a working point on other end, three circular grooves and an extended element having face plate nut heads on the ends thereof. The extended element has at least three identical pairs of partially mutually transversal apertures with mutually perpendicular axes, which cross a longitudinal axis of the extended element at a right angle. The first apertures of each pair of the partially mutually transversal apertures are through and have the same polygonal cross-section, as the prismatic core and the sizes ensuring its sequential placement in said apertures with the possibility of longitudinal movement.
