JIS screwdrivers

Post by CollingsBob » Sat Aug 11, 2018 2:01 pm

Many of us use a Phillips screwdriver on our bikes because the screwheads look like a Phillips...surprise, they arent.
The screwheads are actually “ Japanese Industrial Standard” and use a slightly different screwdriver...

I bought a set of JIS screwdrivers in 4 sizes for short money. If it's Japanese, I JIS the screws. Things like the handlebar brake reservoir cover and clutch hydraulic cover will thank you for using the correct screwdriver.

So, if one were to grind off the tips a bit on a Phillips, might be close to a JIS.... but rather than spend the big bucks on those screwdrivers, why not just change out any JIS hardware to hex or something else... ain't that many on an FJR.... dirt bikes more I'd think. As for those brake/clutch fluid covers, put a bit of anti-seize on the threads and they won't seize in there.... Phillips will work there.

If you’ve never used one, you don’t know how great they are. Worth every penny.

It’s a lot cheaper to buy a few JIS bits than to go through the grief of butchering phillips screwdrivers..

I have both Phillips and JIS screwdrivers, I use the JIS drivers on Phillips head screws and JIS screws most of the time. They don't slip out of the screw head as easily. I believe Phillips head screws and drivers are designed intentionally to let the driver slip out of the head when a specific amount of torque is applied. That is good for tightening but not so good for loosening.

One thing I immediately noticed, which is why I say they are worth every penny, is when you put a screw on it (as if you were putting the screw on and going to poke it into a hard to reach place), the screw is almost locked on it. With a Phillips, you might get 1/2 way to where it needs to be and then the screw falls off. With the JIS, that screw is locked on that end. With a Phillips, you can put the driver in a little crooked and try to turn something. The JIS goes on and it's perfectly straight.

That would be an awesome prize for any gathering, like EOM, etc.

@ Ray, I was able to find quality JIS screwdrivers at a very inexpensive price. My experience with the brake/clutch covers has been a problem with Phillips and a breeze with JIS. FWIW.

@ Geezer, Phillips tips were designed for automated production lines. It was an intentional design feature that the Phillips tip would cam-out (technical term for slipping out) and prevent over torquing.

Ionbeam,

Please, do tell.
Got a link? What was the price?

I like to use Apex-style screwdriver bits where I can. Anybody know a good source for JIS screwdriver bits? The few that I have found on-line are really expensive, often more costly than the JIS screwdrivers.
Cheers,
Red

My first go-to tool place is just a few miles from my house, Plaistow 125 Discount Tools (NH, Rt 125). They sell professional quality tools at a good price. They mostly sell buy-out lots of tools that are new, but it is a walk-in business only. Heck, you can't go wrong going there, one end of the building is a porn shop,the other end is a gun shop and the other side of the parking lot is a Yamaha motorcycle dealer, complete one stop shopping for all of life's basic requirements :lol:

JIS bits $5 for 3 bits.

I can certainly appreciate their usefulness, especially if you can use them on Phillips screws and keep them on the bit. That's similar to the Canadian invention of the Robertson screws and drivers, a square drive with a taper that keeps the screw on the bit. Alas, Mr. Robertson wanted too much to licence it in the US, so it pretty much stayed a Canadian thing. US folks copied it but call it square drive, and now square drive screws are everywhere including here... not the same by any stretch. The Robertson drivers don't work as well with square drive.

The Phillips was a request by Henry Ford, meant to cam out when torque was reached.... naturally, that is a bad thing if you don't want to damage the head. Drywall screws are all Phillips but you use a magnetic tip, and of course, you're not expected to re-use them.

Thanks for the links, JIS looking a lot less expensive than they used to be.... I'm becoming a convert. I still convert to different drive heads, e.g., caliper pins to external hex (Honda part), and 4mm hex fairing fasteners to 5mm (again Honda) to keep from rounding out those hexes so easily on typical fasteners that tend to freeze themselves in aluminum due to bi-metal reaction (anti-seize is your friend too).

Let me ask.... Back in the day when Japanese FJRs came with a tool kit, was the included star pattern screwdriver a JIS or Phillips? (And, why don't I know without going down the garage to look?) :roll:

You know that works on brake and clutch cover screws? A #2 Phillips, and then after you strip the head out of it. Go to your quarter inch drive torx drivers, find the one that is just a hair to large, then hammer that fucker in there!

Then it's a simple matter of getting it out with your driver handle.

If your really a smart guy, you'll put back in the same screw to keep low life's from tampering with your precious fluids.
