Threadlocker or Loctite for crampon frontpoints

I seem to be retightening the bolts holding the frontpoints on my crampons after every 2 or 3 days on the ice.  I tighten the bolts to what feels like an adequate torque and they still loosen after 2 or 3 outings.  I don't want to tighten them like a tire lug nut but I'm fairly sure I apply enough force that they should stay on.  This happens to 2 pairs of Petzl Lynx and to a bunch of BD Cyborgs.  I climb mono on the Petzls and the spacers are all correctly placed.  The Cyborgs are dual points.  
Has anyone experienced this?  
I am thinking of trying some removable Threadlocker or Loctite on them.  Thoughts?

They're nylon lock nuts. I'd just replace the nut as a starting point. Have you examined the bolt and nut off the crampon? They get corroded and worn (especially if they're loose). I have extra bolts and nuts for the Cyborgs. Send me pm and get you some.

Cheers

I use blue Loctite.

+1 for this. Or replace the nuts, as Nylock nuts are not meant to be removed and re-used.

I used Loctite and no loosening after 8 days of climbing.
