1.6 Tightening
Torques
Plastoform screws are used for polymer components and "DG" screws for lightmetal components. These screws form a
permanent thread when they are installed for the first time. They can be removed and installed as often as necessary
without detrimentally affecting the strength of the screwed assembly, providing the specified tightening torque is
observed. For this reason it is
essential to use a torque wrench.

Use the following procedure when refitting a P or DG 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.
1) Torque may be reduced by approx. 1 Nm (0.7 Ibf.ft) when refitting a screw in an existing thread
2) Screw must be secured with adhesive 0786 111 1101 (Loctite 243).
3) A washer must be fitted under the screw head.
Note:
Screws secured with adhesive are easier to release if the adhesive is heated first with a hot air blower (hair dryer).
Exercise caution on polymer components.
