I tried to take mine off as well, some what messed up the screw on one but it should be ok. I saw this hand impact tool in a video and was going to try it out.

i had to drill and tap mine. drill perfectly straight through it with a bit just smaller than the threads. it will come out. Pain in the butt! i left mine out for months before it got around to trying to fix it.
I might pick up matching screws from lowes then do that then. Know what size screws to buy?
I already stripped out one. How do you get these out?!?!![]()
