It is not necessary for an experienced mechanic or locksmith to measure the tightening torque. With experience, he already feels it.
But sometimes on critical nodes you need to control yourself and use a torque wrench
This is especially true for such important components as tightening the main and connecting rod yokes, tightening the flywheel, tightening the cylinder head, tightening the driveshaft nuts, etc.
