Yeah, stripped screws are such a pain in the arsehole. You better use something like a Dremel to remove it, if you have one, of course. Or, a simpler way to remove
Screws – use a drill. Just drill the whole thing out. There’s only one minus – you lose the screw thread and get just a hole. It’s not lethal, but it might be problematic when replacing the old screw with a new one.
But if the screw is welded into the rail, I really can’t see any other variants rather than just making a hole there and then using thread-making drill. There are some good ones that you can use multiple times.
