Majesty tremolo screw

I’ve recently got a used Majesty and unfortunately discovered that the hole on the back of the tremolo (when I dive bomb) that is used to tighten/loosen the tremolo arm (sorry, I don‘t know what it‘s called exactly) is not as it should be. I’ve got another Majesty and I can see the difference. It appears that the previous owner somehow damaged the screw I guess. Is there anything I can do?
