    JIS (Japanese Issue Screwdrivers)

    Picked up a set of these a few weeks ago and have had some time to use them. No more stripping out heads with standard american phillips heads, these things are worth every penny..IMO

    More info...

    A little known, but 'troublesome' standard, the Japanese Industrial Standard (JIS for short) is a Pacific Rim phenomenon. You can never tell where you will find it now - it's everywhere. But start with the Pacific Rim: anything of Asian origin is almost certainly going to include it. The symptom of the problem is when your standard Phillips screwdriver 'hangs up,' and doesn't feel quite right. The Phillips driver won't go into the JIS Screw all the way because the corner radius of the screw is smaller than that of the Phillips scredriver! This is the primary cause of what we know as 'cam-out.'
    Oddly enough, the Phillips standard was created to allow this condition so that you knew you had reaced maximum torque!
    We carry two major brands of JIS Screwdrivers in a variety of formats. Moody Tools, Inc. is Made in Rhode Island. Vessel Tools are made in Japan. We have Moody Tools and Vessel listed separately as well, but this section just concentrates on JIS...

        I have some of those Vessel screwdrivers and love them! Well worth the money.

          My JIS set is made in Germany. They're nice on Japanese amplifiers too.

            I've got the exact same set, just bought from McMaster-Carr. Worth their weight in gold.
            If you don't have a set, get one post haste.

                Yes, but they're pretty low quality, with a useless handle.

                    I bought a set of Hozan JIS screwdrivers a couple years back. They aren't as fancy looking as the Vessel brand but a bit less expensive. They seem to be high quality and server me well. Definitely a worthwhile investment.

                    Thanks,

                      I ordered the Vessel JIS set of 3 screwdrivers for motorcycles from that supplier in the link about 6 months ago. Very fast shipping to this part of the world. I like the feel of the handles on those screwdrivers. Very satisfied with my purchase.

                        What kind of handles do these Hozan JIS screwdrivers have (hard plastic or rubber)?

                              Pretty much eliminated the JIS problem by going to SS allen fasteners where I could.

New SS fasteners through out. Rebuilt carbs, new EBC clutch springs and horn installed. New paint. Motor runs strong.
