Interesting. Apparently if you grind .020 to .030 off the end of a phillips it will do a better job on Japanese screw by going deeper into the slot.
Thanks for the education ridesalot!
Question about JIS screws and drivers: Does anyone know whether old 1960's era Hondas used JIS screws for the side cases? I am doing some long needed projects on my 1967 CB77 (new handlebars, cables, etc.) and I need to pull the side case off. Historically, I used my old trusty Craftsman impact driver with the appropriate sized phillips bit, to break the screws loose.
Thanks, Mike
