Ground screw inverted - Converting 3 prong dryer to 4 prong
You may be able to use a nut with the correct threading, but then you might have to be careful you don’t back the screw out. If it does get backed out and you end up losing it, maybe you could get a replacement grounding screw and put it in head-out when you hook up the ground. Then again, maybe you could use a replacement screw in the hole to the right of the ground symbol.
