ZIMM specifies the following tightening torques for coupling types:

- VWZ-30 / KUZ-KK-16 → 4 Nm
- VWZ-40 / KUZ-KK-24 → 8 Nm
- VWZ-60 / KUZ-KK-32 → 15 Nm
- VWZ-60V / KUZ-KK-35 → 35 Nm
- VWZ-80 / KUZ-KK-45 → 70 Nm
- VWZ-100 / KUZ-KK-60 → 120 Nm

These values ensure a friction-locked connection without overloading the components.
