I have these screws left in the studs from floating shelf brackets. These are two-sided, with the end with the screws going into the studs and the other end with a bolt that the bracket attaches to.
I am trying to remove these from the studs, but there isn't exactly a place for the pliers to grip onto and the since the brackets go in with right-hand/normal threads, I can't use the grip on the brackets either. I'd rather not destroy the threads on the bolt, so I can reuse these later.
So my current idea to keep them usable is to find the correct size reversible/left-handed nuts, attach them and use pliers on the nuts to unscrew them. The last resort would be to use my Dremel and just cut off the ends!
Any other suggestions?
