I’m moving and need to take down my wall mount for my 55in TV. It’s amazon basics and I accidentally mounted it upside down- when I went to correct this, the bottom bolt was too tight to come loose (I guess I was really worried about my new TV falling off the wall!) so I left it as is. But I tried for awhile and in doing so, the head edges became softened and the screwdriver receiving end stripped. I don’t have a vise grip plier at hand. I have a few wrenches. Should I go get one and try it? Though that’s another cost. What’s the likelihood of this thing coming out?
