Technical Term for Bolt Backing Out?
(OP)
Is there a more technical way of saying that a bolt is backing out?
I am writing a service bulletin and want to let the customer know that a bolt tends to back out over time.

We have found that lock wire doesn't really work as a retention device but more like an indicator (if lock wire is broken you bolt is loose.
Nordlocks do work very well but I don't have the counter bore.

I must admit I'm surprised you say you've had lock wire breaking from it backing out only under vibration, though, unless these are fairly small fasteners and thereby requiring a small diameter lock wire. Granted my experience mainly lies in gas turbines in regards to lock wire so you're talking a minimum of 1/8" wire.
In any event, as you said you found a permanent solution so its a moot point, I was just throwing a brain dropping out as curiosity often gets the best of me.
