With the key inserted into the lock (no rotation required), the knob and base hub operate together and can easily be clamped into position or loosened. |

Without the key inserted into the lock, the knob can easily be clamped clockwise into position. However, loosening the knob (counter-clockwise) without the key in position is not possible, the knob head disengages from the knob base therefore, not allowing the threaded insert to release from the mating threaded shaft. |
