Just picked up some mud flaps, got one in but the screw on the other side of my bumper has rounded off so can't get a grip with the screw driver, tried grippers aswell, any ideas?

Grind it or hacksaw across the bolt then take it off with a flat head screwdriver

Finally got it out, used a flat head but used a dremel to grind a groove instead of a hacksaw. I think mud flaps defo improve the look
