Exclamation Use the correct Screwdriver on your bike, Newbie!

Did you know your Japanese motorcycle uses a JIS screwdriver, and NOT a Phillips?
Carburetors, hand controls, engine cases, etc. are actually a Japanese Industrial Standard cross-point screwdriver and not our standard Phillips, as we would think.
Without getting into the technicalities of it, the angles are distinctly different on the head and the US-style tends to strip out the JIS screws due to them not mating perfectly to the shape of the Japanese screws.
There's a lot of information (sometimes conflicting) on why the tips are different and if they are still different or if the latest cross-point screwdrivers are all universal...
Needless to say, it's a fascinating read to study about but I finally decided to buy a set of tips to try in my racheting Snap-On screwdriver before I jump to a set of VESSEL MEGADORA screwdrivers. They REALLY aren't all that expensive for quality tools (roughly $10 per screwdriver) but I do love my Snap-On ratcheting one and tend to use it most of the time (and the little VESSEL JIS cross-point bits were pretty cheap to start with).

Here's the best deal I could find on both the VESSEL JIS bits and the VESSEL MEGADORA JIS screwdrivers.

HERE>>>Maintenance





YES, they work!
I couldn't believe the difference.
My brake reservoir screw held so tight to the tip that it
held my screwdriver up on its own!
I wish I'd have bought these back in middle school! Think of all the motorcycle screws I wrecked!

Lastly, if you think you can buy these locally, think again. I even tried Hardware Sales, and they didn't know what I was talking about... I think maybe online shopping is the only way.

Alas, Thumper, in spite of your name I might hazard a guess that you may not be old enough to have experienced British cars and bikes in their heyday. Japanese screwdrivers would have been the least of your problems if you did not have a good collection of Whitworth tools.

Ahh, no. My dad had a Bultaco, Triumph, and a few others from that era. I do have a '71 Husky Sportsman that is slightly older than I. He always had a hodgepodge of tools; I don't think I'd recognize in his collection any specialty tools that he used back in those days...

I will admit I knew about JIS screwdrivers for eons but hadn't ever sought out sourcing some. The internet is really pretty cool, isn't it!

Wow, spooky. I just ordered the Vessel 220w-3 handle + bits; it comes with crosspoint #s 1, 2, 3, plus one flatblade and #s 2 and 3 posidrive tips. It arrived yesterday. I've tried it out and while it's a little shorter than it might be, the ball grip is nice and torquey, and since the tips are hex you can use them in another handle or the hex socket drive trick if you need more length. Nowhere does it say JIS on them but I have a reasonable trust that unless otherwise indicated these will be Japanese standard by default: just about all the reviews say so, for what that's worth.

Further to that, it's worth mentioning what it says on the Vessel website, explaining why they're not actually labeled JIS:

Quote:
As you might know, VESSEL is the oldest screwdriver manufacturer in Japan, and made a contribution to set a Japanese Industrial Standard (JIS) standard.

We do follow JIS (Japanese Industrial Standard) standard for cross point screwdrivers. Because the technology to manufacture screwdrivers in Japan had already become above a certain level, JIS (Japanese Industrial Standard) recognition system for screwdrivers became extinct in 2008.

So there is no authorized JIS (Japanese Industrial Standard) manufacturer now, and we therefore cannot print "JIS" mark on our screwdrivers.
So if I read that right, there's no longer a certifying process so they don't label it as such, but it's a safe bet that any Vessel brand crosspoint screwdriver will be JIS compliant unless otherwise labeled (e.g. posidrive.)

I'm just guessing here, as my Kat has JIS screw heads all over it, but I'd bet that almost any European brand of bike doesn't use JIS screw heads....unless they are made in Japan.

Many JIS fasteners have a dot stamped into their heads. If you see a dot and try to remove the screw with a phillips driver you stand a pretty good chance of buggering it up, especially if the threads are corroded. A set of four JIS screwdrivers is about $20 on Amazon. Bits are cheaper.

Is it applicable only for Japanese bikes? Triumphs and Ducatis use standard Philips, correct? Or does it depend on the origin of the part?

It definitely depends on the origin of the part...

I didn't get into all the technicalities but, yes, the JIS screws tend to have a small "dot" next to one of the points. (As MMCN49 noted).
This topic on JIS screwdrivers tends to attract a fair amount of discussion online. Needless to say, you can't go wrong using JIS screwdrivers as they are the tool of the manufacturers, though (obviously) many people do use Phillips.
There were other types of tools used on European bikes years ago, but I don't think they use them anymore.
