Popis:	1. It was established that a compressed-stretched figured nut is preferred over a compressed cylindrical nut (the safety factors for stresses KN at the tie bolt thread root were 34 and 13, respectively). 2. In the figured nut, the last turn is maximally stressed and the average pressure on the side surface is 440 MPa. For reducing the load on the last turn with a view to increase the reliability of the joint, it is suggested that a bush be press fitted into the end part of the nut which is free of the thread. The calculation showed that this leads to redistribution of the load and a reduction in the pressure on the last turn to 390 MPa.
