John Deere did a practical engineering study of different methods of
locking bolts on test rigs. Lockwashers and locking tabs were
virtually worthless, Loctite worked pretty well. They stopped using
lockwashers and locking tabs and had loads of loctite in the factory
to use instead.
So, what Randall said.
