I have tested this product and it does not work. When exposed to severe vibrations the insert ring (with the hooks) starts to slide towards the nut. Same locking result as for nylon insert nut or Metlock.
Be careful with Loctite! It may act as a lubricant but also as what it actually is, an adhesive. Depending what Kind of Loctite (red, green, blue) and how much you put on the threads it will cause a great deviation in preload for a predefined torque.
Most locking systems based on increased...
We have solved many "fatigue sensitive joints" using Nord-Lock washers, since they actually keep the preload in the joint at its initially level.
The damage you get in the base material is pure impression marks, no scratching like one-piece serrated washers. When tightening it slides...
