Thanks Peter, i´ve divided the bolt in two and did what you said. But i have a problem, how much force do i need to apply in the preload? Because it has a diameter of 8mm and the tightening torque is 31Nm and if i apply the T=dxkxF formula (F being the preload) the force is around 25KN[KN] and with this force, both legs broke because of the stress. And lastly, the 1 and 2 steps that you said are an automatic tool or i need to put them manually?
