When inserting DG and P screws into an existing screw thread:
Insert the DG or P screw in the hole and turn counterclockwise until it gently drops into the hole in axial direction.
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.
As a rule, microencapsulated screws must be replaced after removal.
Screwdriver speed when used in plastic material: max. 500 rpm for DG and P-type screws.
Do not use an impact wrench to release or tighten screw connections.
Screws with and without locking serration must not be confused.
