• Flange nuts and flange bolts of strength classes 10.9 and
10.
• Flange nuts and flange bolts of strength classes 12.9 and
12.
• Clamping flange nuts and flange bolts of strength classes
12.9 and 12.
1.1.4 THREADED CONNECTION 10.9/10
As standard, a 10.9/10 threaded connection is tightened to a
specified torque followed by an additional rotation. The addi-
tional rotation depends on the length of the bolt. See “Tight-
ening torques” for the tightening torque and the appropriate
additional rotation.
If one of these 10.9/10 threaded connections must be tight-
ened to a different tightening torque, then this will be stated
in the technical information for the component concerned.
1.1.5 OTHER THREADED CONNECTIONS
The 8.8/8 and 12.9/12 threaded connections and the 12.9/12
clamping flange bolt are usually only tightened to the stand-
ard tightening torques. See “Tightening torques” for the
standard tightening torques.
If one of these threaded connections must be tightened to a
different tightening torque, then this will be stated in the tech-
nical information for the component concerned.
1.1.6 REUSING FIXINGS (NUTS/BOLTS/THREADED
ENDS)
To obtain the correct pretension when reusing a threaded
connection, the following procedure must be followed:
1. Clean the thread (take particular care to remove any
locking compound residue) and the fitting faces.
2. Check the thread for damage.
To do so, screw on a new nut/bolt by hand.
If the new nut/bolt cannot be screwed along the entire
length of the thread that is being checked, then the fixing
may no longer be reused.
3. Apply one drop of engine oil to the first winding of the bolt
(threaded end)/bottom winding of the nut and one drop to
the fitting faces.
Not observing the instructions given
below may result in the bolt connections
coming loose. This can cause damage to
the vehicle and lead to a dangerous
situation.
