I don't know. I have taken my clip completely off my Benchmade and then back on again. No loosening. Maybe I've just been lucky. I do have to occasionally retighten the pivot screw, but mostly only after an accidental trip through the laundry.
Maybe I'm not remembering this correctly, it's been a while, but I'm thinking that I once used a Loctite formula for something else, and that it was in between the blue and the permanent red one in terms of bonding strength. I think it was green, but I don't think you can really go off of the colors, because they have some different formulations that are the same color, IIRC.
Have you tried wrapping a tiny piece of tape or something around the screws? Kind of make-shift, but at least it might keep you from losing any hardware until you find a better solution.
If nothing else, send an email to Benchmade and Emerson. I'd bet either one would take care of it somehow.
