led an exploratory investigation of bolts in curvic couplings with rotational cross over stacking. This examination included testing of 51 mm (2 in.) long dashes with a distance across of 5.71 mm (3/32 in.) and bolt head measurement of 8.88 mm (3/8 in.). The outcomes affirmed that extricating because of cyclic cross over stacking might be started through restricted slip without complete slip at the screw head and that self-revolution of the nut happens without complete slip of the fastener head.
