that screw head is and easy fix. You will need a small piece of steel with a threaded hole to match the screw and a very small ball peen hammer with a polished face. Screw the screw in to the hole and very lightly tap on the screw head where the metal is lifted until flush, then a thin needle file to lightly clean up the slot and your done, done properly you will never notice it.
