Hi Terry, Some Canadian pianos, do have the Robertson screw for the flanges. I saw a documentary on that screw, and its inventor. He had them try it on a Model T Ford, I think it was. They saved time, but Henry Ford wanted the patent or control, and the inventor, wanted to retain control, so Henry said no. Otherwise the Robertson, and not the Phillips, would be the predominant screw. Ok, maybe slot. Regards, John M.
