Important repair information
Bolts with locking splines, micro-encapsulated bolts and self-locking nuts must always be replaced after being used once.
There is an increased risk of injury when unscrewing micro-encapsulated bolts due to the sudden breakaway torque.
Before new micro-encapsulated bolts are screwed in, the mating thread must be re-cut in order to remove all the residue of the old bolt locking compound.
