Vibration loosening of fasteners
Vibration loosening of fasteners
(OP)
Anyone with proven devices or methods for preventing vibration loosening of fasteners? The flanged connections I work with are subject to extreme vibration, and I'm looking for tips for preventing the nuts from loosening. These fasteners must be re-torqued periodically for PM and inspection, so I can't spot weld the nuts to the flanges. Any tips/ideas?

The damage you get in the base material is pure impression marks, no scratching like one-piece serrated washers. When tightening it slides on the head of the bolt and when undoing the joint it slides on the cam faces (between the pair of washers). In addition, the serrations on Nord-Lockâ washers are shaped as fish scale for minimum damage of mating material.
This is a high tech locking system, which uses geometry to lock!
