Use the following procedure to fit a DG screw in an existing thread:
– Place the DG screw in the hole and rotate it counterclockwise until 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,
which would weaken the assembly.
Note:
Power screwdriver speed setting for polymer:
– DG screws max. 500 rpm
