If the damage consists of metal from the screw slot being lifted up
etc. it is surprising how much it can be improved by removing the screw,putting it in a vice, and working carefully with a small flat faced punch and hammer to move the metal back into the slot.
Touching up the slot with a screw slot file and a little aging
will make a big difference. Maybe not perfect, but a lot easier on the eyes if you don't want to go the weld/engrave route.

Better to keep your mouth shut and be thought stupid,than open it and confirm.
