Since th OP was already picking out what replacement screw to use I thought the stripped screw was out.

If the Socket Head is stripped I don't see why and Eeezie Out type too would not work. You just need to pic one of the types that seems like it will work and try it.

Then there is a few Members who have said you can Beat in a Torqx type bit and use that like an Eeesie out. That appears to work on the Motor Mount Bolts.
