I've got a problem with my toe clips. Specifically, the clip on the pedal that I take a foot out of when stopped at a light or something, so it gets flipped around more often and just generally gets more abuse than the other pedal clip. The problem is that the mounting bolts back themselves out regularly, and I've now had to replace the bolts several times because I lost one during a ride. Consequently, the clip has gotten damaged from being used with only one bolt, so I'm getting new clips, the MKS clips from your site.

Anyway, the question is: is it a common problem for the clip mounting bolts to back themselves out, or did I just have cruddy hardware? And if it is a common problem, is there a common solution? I'd thought of loc-tite, but didn't want to do something so...permanent.
