I think your Cobalt is an '08? Still pretty young. Anyway, the screw holes are pretty small and should have no effect on the car's lifespan.
I'm using #8 sheet metal screws with phillips heads and molded-on 'washers". Plus fender washers as I mentioned. Maybe should be stainless but that's another subtopic. Anyway, the drill holes for those are pretty small - I'm using 5/64". They're all on the underside of course. Most are into plastic such as the bumper cover. A few are into the framing members that are stamped onto the car's underbody panel.
