Hey so the little bolts that hold the crank to my new 48 tooth chainring keep loosening themselves.

This is a SuperMaxy crank and chainring that I cannibalized from a touring bike (ie, there were two smaller inner chainrings that I removed). The large chainring is held on to the crank by its own set of bolts.



I'm guessing that they keep loosening because it was meant for touring use and not designed for the stress/strain of fixed riding? Anyways what should I do? Should I just find a one-piece chainring or should I try cementing the bolts in place with some threadlocker?

And no, those arent the original bolts. I know its super ghetto, but I got the 'ring and crank for basically free so I want to ask whether its worth trying to make this work or just get a proper crank and chainring.

thx
