    slipping screwdriver

    This concerns those Jap screws that like to strip if you dont have the right driver. Before i attempt to strip one I put a small spot of valve grinding compound in the grooves This helps greatly to grip the driver to the screw. I hope this helps anyone. Happy Trails

    Had the same trouble with phillips head screws! Had to grind the last one off when it burred I intend to replace all the phillips heads with allen heads... no more burred screws! However, I'll give your method a go next time I have to remove one.

          You also should remember that Asian philips head screws are different than North American philips head screws, so often you need to check that you have the proper screwdriver bit to properly work on your bike.

            He actually covered that in the very first line of this thread.

              i find that i can get away with using ANSI screwdrivers on JIS screws if I'm careful, but I'm curious to how the big guys do it, as in guys with nice garage setups-do you use philips, jis screwdrivers and/or jis bit ends?

                I work with 24 techs. All have limited Japanese background as well as German stuff. None have ever heard of Japanese type screwdriver tips being different.
                All of them have told me that when they don't have access to their impact drivers, they do it this way: spray with something like Rustoff or Pblaster, wait 5 minutes, whack squarely with at least a 1 lb. hammer, wait 10 minutes, lock on with vice grips OR use the tightest firring phillips bit you can find and push it AGAINST the screw gead while turning.

                  nice, i was told banging the screw would free the corrosion. good to know this is true.

                    A while back, there was a thread on the difference between Japanese screwdrivers and American/DIN. I bought three Phillips screwdrivers made to the Japanese standard. While I can see a slight difference in the shape of the tips (or at least I think that I can) I've been unable to detect any difference at all in how well they grip screws, either American or Japanese. Maybe the manufacturing tolerances on the screws are too sloppy for precision tools to make such a difference.

                      Tha Jap Phillips are not in fact Phillips at all - looks like a Phillips screw, but are designed not to cam out (useful for robot assembly lines). Heads are usually identifiable by a single dot to one side of the cross slot. Their correct name is JIS - all a bit technical but have a look at:

                            If you ever want to compare these cross slotted screws, use one of those screwdriver bit sets. They usually have a large selection of every type of bit with short hexagon shafts. You can then compare the fit to each type of crosscut screw head and will be surprised at the difference. Once you have the right one check the size stamped on it and there you have it.

                            The trick is to use a very long shaft screwdriver rather than a short one, even if the bit is the same. If you need to move tight screws always use the longest shaft screwdriver that can get in there.
