In a steel truss bridge, the fixed torque electric wrench must adjust its torque before applying the screw.
The torque is not very standardized. In the big six angle high strength bolt, the main words are torque, preload and axial force. Torque is often used in conjunction with torque.
In the case of a torque factor tester on site, it is feasible to calibrate the axial force in one step.
