Torque wrench
-
Have torque wrenches regularly inspected
and calibrated.
Re-use of fasteners (bolt/nut/threaded end)
1.
Clean the thread (take particular care to
remove locking compound residues) and the
clamping faces
2.
Check the thread for damage.
To do so, manually screw a new nut/bolt onto
the thread to be checked.
If the new nut/bolt cannot be fully hand-
screwed onto the entire thread of the
fastener to be checked, the fastener is not
allowed to be re-used.
3.
Apply one drop of engine oil to the upper turn
of the bolt (threaded end)/lower turn of the
nut and one drop to the clamping faces
(other lubricants are not allowed).
4.
If a locking compound has been specified, oil
should not be applied to the thread.
