Bolted Joint – Wikipedia, The Free Encyclopedia
Torque wrenches do not give a direct measurement of the clamping force in the screw, and indeed much of the force applied is lost just to overcoming friction. is quite similar to the construction of an electric motor, and hence a motor can be directly used to provide the torque.
