I'm gonna try to get this thing out first.
I read a bunch about this after I posted it and learned that the stud doesn't go all the way through and also learned that it's a stud and NOT a bolt. I tried to grab it with pliers, but like usual, it broke off flush so that didn't do anything. I'm going to try to get a backout or something from home depot to see if that works. Here's to trying.
