Abstract

The herein disclosed self-secured nut is characterised by the possibility of changing the geometry of its thread pitch in respect to the thread pitch of the screw (fig.1, 2-10) thanks to the thinning down of the internal thread part (fig.1-5) being in contact with the screw thread having the same pitch. The pitch changes upon inclination (torque) created during the rotation of the aforementioned parts; the internal part is secured with the external one in order to form a unified compact body not rotating around the screw thread. The invention ensures the complete securing of the assembly (fig.1,2/2,3) capable of being secured even with no surfaces on the screw thread, this last being unable to rotate.
