When inserting the DG and P-type screws in an existing thread:
– Insert the DG or P-type screw in the hole and turn it anticlockwise until it gently drops into the hole in axial
direction.
– Turn screw in clockwise and tighten with the specified torque,
This ensures that the screw engages the existing thread and does not cut a new thread, thus preserving the
strength of the screw connection,
