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.
Coat micro-encapsulated screws with medium-strength threadlocking adhesive before re-installing.
This procedure ensures that the screw engages properly in the existing thread and does not form a new thread
and weaken the assembly.
