Tightening torque: 4 Nm
For ease of installation and removal the rod connection can be rotated
without restriction. Even if rotated several times there is no risk of
damage to the device.
In case of high mechanical stress (strong vibration, moving viscous media) it may be necessary to
secure the screw connection, e.g. by a screw retaining compound.
