The article presents the results of research on the original screwdriver for industrial applications in the event of the need to obtain the value of tightening torque in narrower tolerances. The operating of the screwdriver is supervised by the control program, which has algorithms implemented for selecting the operating mode. The program also allows archiving operating parameters and visualization of on-line characteristics of screwing. The results allowing to verify the adequacy of the mathematical model of screwdriver operation with actual operating conditions are also presented.
