Applications
The above-mentioned tightening torques apply for the following applications:
● Case A
Applies to electrical connections in which the permissible torque is normally limited by the
bolt materials and/or the current carrying capacity of the insulators, with the exception of the
busbar connections in case B.
● Case B
Applies to bolts screwed into components made from materials with lower property class
(e. g. aluminum) and to bolts with property class 8.8 according to ISO 898-1.
● Case C
Applies to bolts with property class 8.8, A4-70 or A4-80 according to ISO 898-1, however
only to bolts screwed into components made from materials with higher property class, e.g.
cast iron, steel or cast steel.
Note
Non-standard tightening torques
Different tightening torques for electrical connections and bolted connections for parts with
flat seals or insulating parts are specified in the relevant sections and drawings.
