Hello,
Building an interior wall with wooden studs, I had just screwed the stud to the ceiling with two mounting screws 8x100 and was about to create a third hole. I thought I would remove the latest screw to drill more easily by moving the stud 30 degrees while making the hole.
Used the screwdriver and now the head of the screw is completely stripped... There's absolutely no grip, and trying to hammer in or pull out the screw is futile. Is there any way to get it out? What do I do later when the wall needs to come down and that screw needs to be removed...
