Define Tightening Safety Levels
| Screw Classification | Harmfulness | Common Stations | Requirements for Screw Driver |
| Class-A Safe& Important | Connection failure→casualties | Braking/steering system, engine, tyre, safety belt, seat etc. | Simultaneous torque/rotation angle measurement, real data feedback, data recording and tracing, NG fault identification 5%(Torque accuracy) |
| Class-B Importan | Connection failure→dysfunction | Wiper Panel air conditioner etc. | Torque or angle control, Ensure tightening torque and quantity correct. NG Fault identification. 5-10%(Torque accuracy) |
| Class-B Importan | Connection failure→customer complaints | Interior parts such as car trunk, sunroof and sun visor | Torque or angle control, Ensure tightening torque correct. 10-20%(Torque accuracy) |
