Use the following procedure when refitting a DG or P screw in an existing thread:
Place the screw in the hole and rotate it counterclockwise until it drops down slightly.
Tighten the screw clockwise to the specified torque.
This procedure ensures that the screw engages properly in the existing thread and does not form a new thread
and weaken the assembly.
Before reinstalling a micro-encapsulated screw, clean both threads (screw tap into female thread by hand and
then blow out with compressed air, clean male thread with brush), coat clean screw with medium strength
Loctite 242 or 243.
Power screwdriver setting for polymer: DG and P screws max. 500 rpm
Do not use an impact wrench for releasing or tightening screws.
