You can get impacts that only tighten by torque intervals. So it won’t just spin it on really fast it will spin then stop and if you keep going it’ll spin it on tighter then stop. It’s tightening by torque intervals so it won’t over tighten unless you just keep on going usually three full rotations of the lug nut is enough. But if you do use an impact you can check it with the torque wrench
