Well learn something new everyday....jis stands for Japanese Industrial Standard and apparently Japanes screws are not really phillips head but JIS head. 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.
