Rotor set screws coming loose?

I just installed new front rotors and pads, and they're having the same issue as the last - the set screw comes loose and the rotor has a bit of play that makes the front end suspension sound clunky. Anyone else ever have this issue?

FCABs are 5k miles new, new front hubs rotors and pads, as well as new sway links. No noticeable play in wheels when in the air.

the screw is only for mounting purposes, shouldn't affect the rotor if not even installed

OP, I'd use a metric tap to clean out the threads in the hub. Those screws should back out unless they weren't properly torqued. Also, use a bit of anti-seize on the set screws.

This. It's there for convenience and is not meant to keep the rotor attached. If you can move the rotor with the wheel attached then you have bigger issues.

So I have an annoying clunky sound and this is what I found. They are pretty cheap to replace. I think rockauto.com had em for under $20 a piece. I'm replacing them tomorrow if I get to it. I realize yours are new tho.
