This video shows the comparison between various ways of locking nuts.  
The reaction to a lock washer and vibration was a real surprine. Only 
one method actually worked.

##  I dont think you will loosen bolts and nuts when  blue loctite is used.... and esp red loctite.
They should re-run the tests again, but using a flat washer under everything.   Also, what else
that might work is double nutting, but using  2 x nylocks. 

##  It appears that they used never seize goop on the threads.   That alone should reduce the required
Torque by a good  33-40%.   It would be interesting to place your fingers on the assy, shown in the video, while
it is vibrating away.   If stuff is vibrating loose within 2-20 secs, it must be one helluva vibration, not some subtle,
gentler, vibration. 

##  Note, there are several other cos that make identical washers as the nordlocks..and no where near the price tag. 
There is only one correct way to install the pair of nordlock washers..and several wrong ways.
