Abstract
Not only difference of deformation of bolt rod (tension) and nut (compression) but non-uniform in height radial extension of nut and compression of thread part of the rod, nut body twisting in radial plane and above all irregular pitch due to production irregular has an impact on force distribution in thread. It should not strive for a precise production of thread with uniform pitch but on the contrary, due to control irregular thread pitch full-strength of thread can be reach. Our numerical investigation shows, that using of control irregular thread pitch can decrease maximal stresses by 50% in comparison with precisely produced thread.
