3.5 Tightening torques
DG and P screws are fitted in plastic and light alloy metal parts. These screws form a permanent thread when
they are installed for the first time. The material is permanently deformed. Screws can be removed and installed
as often as necessary without impairing the strength of the screwed assembly, provided that the specified
tightening torque is observed.
For this reason, it is essential to use a torque wrench.
