3.5 Tightening Torques
DG screws are used in the polymer and light-alloy 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 always use a torque wrench.
