Screws and nuts
In general, it is recommended to make connections of the the same type and class as those foreseen for similar fastenings on
the original vehicle (Table 2.4).
Screws of class
8.8
and
10.9
must be hardened and tempered and, for applications with diameter
≤
6 mm, it is recommended to
use stainless steel parts.
The foreseen coatings are Geomet and galvanisation. If the screws are subjected to welding, the Geomet coating is not
recommended.
If space permits, use screws and nuts with a flanged head.
Use nuts with loosening prevention systems and remember that the tightening torque must be applied to the nut.
