A.4 Tightening procedure Tightening procedure
Tightening torques must be observed taking into account the following table:
Scatter of the torque ap-
plied at the tool
Tightening procedure
(As a rule, the tightening procedures listed are within the spe-
cified tool torque scatter.)
±5% • Hydraulic tightening with mechanical screwdriver
• Torque-controlled tightening with a torque wrench or a torque
wrench that gives a signal
• Tightening with a precision mechanical screwdriver with dynamic
torque measurement
TableA-12: Tightening procedure
The tightening torques apply to screws/bolts with untreated surfaces that are not oiled or are
only lightly oiled, and for screws/bolts that are used with a liquid screw locking agent in ac-
cordance with these instructions. Use with lubricant paint or lubricant is not permitted.
