Hello Josh M. That should be ¾" flat-head screws rather than ½" flathead screws. If you get square-head #8 Robertson screws (a good Canuck invention!), you can quickly remove the screws with a screwdriver bit and your cordless drill. However, when installing the screws, you have to be a bit careful as you can crack the Plexiglas by torquing the screws in too tight. Even if you install and remove the screws by hand, it doesn't take that long. Bob M.
