ok guys... I had a nice sun shiny day, and the kids were playing outside so I started taking a few things off this old bolt.
well that didn't last too long cuz it is still pretty cold, and the kids got soaked. in the meantime I found these screws with a head that I don't have a tool for.
what kind of screw heads are these, and how common are the tools to remove them? (I bet ya they aren't going back in)
