Always fasten the bolted connection by turning the bolt head! When checking
the pre-stress of the bolts, it has to be considered that constraints and frictional
forces can lead to a loss of clamping force. This was taken into consideration when
the tightening torques were determined. When a bolted connection is checked, it
must not loosen when 50% of the specifi ed tightening torque is applied.
