Hi,
FWIW I toasted my left crank - it just wouldn't stay tight.
It had got loose and was clearly damaged from being loose.
Tightening the nut just didn't work, quickly came loose.
Cheap bike so I went for a cheap solution. Cleaned up
the worst of the damage on the crank with a file and
used a small amount of two part epoxy as a filler
and threadlock*. Worked a treat - its now fine.

To be precise I tightened up the nut and then took it off,
and applied further epoxy into the corners of the bracket.
I was going to leave it like that to set but noticed I'd
got some epoxy onto the castelled surface of the
washer integrated with the nut, so I thought sod
it and refitted the nut tight before it all set.
So not really used as threadlock, but similar.
