This is another screw that also gets stuck. It keeps getting tightened as the friction material wears down. When it bottoms out, it gets stuck. Then when you try to back it out half of the head snaps off. I used to make plugs from trimmer line (boathouse repair) to move the screw back out some, but now I just snip off a piece or two and drop them in the hole. Seems to work OK.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
