JIS - Japanese Industry Standard screws

[XXitanium]

Japanese Industry Standard screws...  Not a phillips....

 

I looked around and didn't see an actual thread with this topic. I saw Swampnut had mentioned it in a garage thread.

 

I don't know it I could discern one driver from the other

I've mostly decided that there's no reason to own a Phillips screwdriver, yet I have a shit ton more of them than JIS drivers.  The few times I've tried a JIS driver on a Phillips screw it did better than a Phillips screwdriver did.

[superhawk996]

Oh, and to tell the difference on the screw; from my understanding the JIS screws always have a dot stamped into them.  Look at any Phillips looking screw on a Jap vehicle and you'll likely see a dot denoting that it's a JIS.

Thanks, I did get the screw ID from the article above.

JIS is one of those life-changing discoveries like small flush-cutting dykes.  I've had a set of drivers for a while, and just recently got bits that I need to deploy into the power drivers.  I lost one size, and learned that unlike Phillips, JIS sizes will moderately interchange.  That is, on a normal torque screw, they still work.  Haven't tried something really stuck.

That's a good link.  On most of my #0 and #1 Phillips sizes, I have ground just a little metal off the tips, and they seem to fit the JIS much better, if not perfect.  Here I thought the screw driver and bit manufacturers were just doing it wrong.  Now I know.

Had to read that a couple of times.  😳

I've had a Snap-On #2 Phillips bit for about 45 years now, it's #SDM222BZ.  I can't find it online by that model number, but it is similar to their SDM222IRB.  It once had little ribs that helped keep it from camming out of a worn Phillips screw, they're long worn off by now.  It came in a ratcheting screwdriver kit that I bought when I was in the Coast Guard.  I didn't have much money then, but it seems to have paid off buying the good stuff.  I can also recommend their #EXDL10A left-hand cobalt-alloy drill bits with matching screw extractors - many times, when drilling a screw to extract, it would just start backing out without having to even use the extractor on it. 

 

I know it's remarkable to have such a tiny, easily-lost tool hang around for that long, but there's a reason; this is by far the most effective driver tip I've ever used.  Other guys would wreck screws with poor quality drivers, this thing would take them out with no effort.  It also for some reason is very effective on JIS screws, it never put sharp edges on the grooves of any of the fasteners on my Jap motorcycle - so I never found a need to invest in JIS bits or screwdrivers. 

 

I think I've got my money out of it, should probably get a new one.

I've had both of those tools for about half the time you have.  I got the screwdriver set as a company Christmas party gift, it came with a matching green Mini Maglight.  My bit still has the ribs.  I've lost track of the other bits it came with, but that one was special enough that it's still around.  The cap for the screwdriver no longer stays, it was kinda loose fitting to start with and the threads stripped out.  That bit lives in the driver, when I use it or the driver for something else they get reunited immediately after.

 

More recently I discovered Craftsman screwdrivers with diamond encrusted tips, they grip quite well.  I broke one of the drill bits from my extractor set years ago and never got around to replacing it.  It's awesome when drilling for extraction and the extraction just happens.

And some new keycaps.  You should walk into an Apple Store and ask nicely.  At least for Moriah, they've always been free.

Another must have.  So much so that my friend's coworkers all say "hand me the life-changers" after I introduced him and his crew to them.

I have the Exelite version of those.  They're da bomb for cutting wire ties if you don't need them pulled tight or if there's no room to get in with a wire tie tool.  No more looking like a multiple failed suicide attempt after reaching up under your newly-wired dash.

I beat the shit out of the #3 with a sledgehammer,  to loosen the rotor retaining screws on the wifes Civic after 7 years of Northeast winters.  Worked great.

 

Motion pro has some JIS insert bits

I have a set of the vessel megadora JIS drivers, they are fantastic and should be mandatory in the toolkit of anyone working on Jap bikes of a certain age

They weren't too expensive, the set of 6 was about £36

 

No problem for a man of your means  

[CALCXX]

I blamed it on Honda in the 70's. I became quite the expert using a chisel or an "easy out"  

[rockmeupto125]

Cal, if you had just used the tool kit that came with the bike.....

 

 

 

But I had my favorite little half round chisel that would bite into those soft screwheads.

Unfortunately not always in my experience, in most cases this is true though.  I tend to defer to JIS when working on my 80s/90s jap sportbikes.

I recently discovered Presch files and Rasps, a german brand at a reasonable price point.  I'm a huge fan of Wera tools as well but have very few of them as I struggle to justify the pricing for home use.  If I was a professional spanner swinger it would be Wera all the way, their Zyklop ratchets are simply excellent.  I have a stainless steel bit set and some joker spanners along with a smaller bit set and bit driver from them.
