Abstract (en)
[origin: WO2019012491A1] The subject matter of the invention is a shaped ring nut dedicated to bolt connections used to connect machine and device elements. According to the invention, the essence of the solution lies in the fact that on one side on the frontal surface, the nut has an additional ring of any external shape allowing the elimination of the degree of freedom being the rotation of the nut around its own axis. An additional ring of any shape is installed in a shaped hole made in one of the connected elements. The outer shape of the additional ring is any regular polygon, in particular a triangle, a quadrangle, a pentagon, a hexagon, an irregular polygon, a star polygon or the outer shape of the additional ring is any oval.
