I've been working around a 3/8-16 bolt since it's going into plastic. Coarse, big threads are the order of the day for us.
Are you doing this within one frame member like 968 in 2006, or 60 in various years; or are you doing it like 114?

If like 60, we used that tensioning setup with a #10 and it wouldn't vibrate loose that much. Usually 1-2 times a regional we'd check and the chain was slightly loose, we would it half a turn or so, and be good to go. We use the same concept on our with no problems (also ran it in 2007, had to tighten it about as much as in 2006).

So, short answer. No, it shouldn't loosen much and it should work just fine. Over the various years we've used this method, I've never seen it loosen so much over the course of one match to actual cause any problems.
