Mine were loose, and rather than take them out and replace with normal, I was stupid and tightened them up

When the head breaks off it leaves a rough surface. I used a screwdriver and a scratch awl to "get a hold" of little bumps and rotate it that way... Something like a pencil eraser may also be able to get a bit of grip and spin them if they are already loose???
