Not trying to be a buzzkill here, but I ran out to harbor freight and bought the screwdriver kit suggested above and they are not JIS. I was hoping they would be but at least now I have some more cheap scredrivers that I can "massage" to work like a JIS.

JIS Screwdrivers

Post by NKYWinger » Thu Mar 14, 2013 8:17 am

I found this article about JIS screwdrivers- it explains why our Phillips never seem to fit quite right! Always wondered 'bout that.....

I've had a set of JIS screwdrivers for a few year now. If you have anything Japanese they are a must have. Wish previous owners of my bikes had known about them. Had to drill out one screw that had been totally chewed out.

The JIS screwdrivers fit the GW screws so well, it's almost like the screwdrivers are magnetized - they hold the screws that tight!

Ordered a set of three #01 #02 and #03 on the fourth day of March, in the year of our lord two thousand thirteen.

I received them finally, last Thursday - which was 28 March 2013. I appreciate having received them, but I sure will not order from that guy again. They came from Lansing, MI. That is only about 400 miles from me.

Harbor Freight doesn't have JIS style, but you can get them here...http://www.vesseltools.com/ Pretty expensive, but I'm going to order some because the right tool for the right job is always much less frustrating.

Or you can do like some of us have done, and get a cheap set and modify them to fit pretty well.

Here is the url to the HF website for those screwdrivers.

http://www.harborfreight.com/32-piece-s ... 90764.html

I don't know why the folks here say they are not JIS. Are they actually measuring the angle and the dimensions? I have two sets and they fit the JIS screws on my Goldwings perfectly. So if they are not JIS they sure are as close as I've found anywhere. I may have to break down and buy a #2 vessel just to see for myself.

I bought two sets from one of the first sources mentioned on here. One for me and another for my son to use at the bike shop along with his bike. I hated to pay $38/set, but after using them, they were worth every penny.

For example, when I was hooking back up the carbs, I used the regular Craftsmen driver and then one of the JIS to see how they felt on the same screws. Night and day.

If you are going to work on a metric Japanese bike, you have to have these. I just wish I knew about them a long time ago.

I will have to buy a set of these that you listed. My buddy has a set of JIS and when I use them, the feel in the slot is perfect, and I have a few screwdrivers that are close, but the JIS are like NO movement in the screw head at all. But if the ones you list work, I'll save some bucks. Many of the heads of my screws were somewhat buggered up from previous people using the wrong drivers, and that may be why the JIS feel so much better. Thanks for the link.

At the top of the thread I posted a degree measurement derived from my plastic mold of a JIS screw. I suggested 57 degrees.

According to this drawing the recommended angle is (90 - 26) 64 degrees. I presume the drawing is accurate.

JIS bit ground for an impact driver.

Photo after use. The bit conforms to the screw head after use.

I think going to a hair over 52 degrees is most effective.

The Harber Fgt kit does have bits that will work.
I've found also that sometimes the multi 1/4"-bit sets you get with a new drill or with other accessories have not only the phillips #PH1,2&3, but a set of PZ1,2&3.
The "PZ" bits (also called pozi-driv) are like the JIS! Just need to use a 1/4" nutdriver with them.
I also use them with an impact driver to remove and chuck them in a cordless drill when re-installing and set the torque low.
They do have a second set of 4 angled blades in between the standard blades, but usually don't hit the screwhead.

Bump. After 1,000 + views there must be some interest by google search.

I submit that the small dimple (or dot) is to identify the thread as ISO, as opposed to the JIS thread used on most fasteners on Japanese motorcycles prior to 1967. See Service Letter #74, Change of Threaded Parts, dated 6/8/67.

Thanks for this

http://www.search-document.com/pdf/1/8/ ... sizes.html

Thread pitch changes to ISO are identified by a hemispheric embossment in the 3, 4 and 5 mm size cross head screws.

Other items are also identified that affect interchangeability.

I can still feel the pain stabbing the inside of my index finger as the best Phillips I have, to tighten up the small fuel line type Japanese hose clamp, slips. I usually try again with the same Phillips (insanity at its best) before I go and get out the tool kit and get the small Phillips and slip it on the handle and go back in. Fits perfect. Oh yeah..there metric. All these years, around motorcycle's, never thought of or new of JIS. My set is on its way. I wonder if they make a Whitworth Phillips?

Remember that the Goldwing motorcycle has a JIS screwdriver that came with the tool kit for the bike. The few JIS screws on the bike can easily be taken care off with the tool kit.

The good old fashioned impact driver works just as well. The El Cheapo kind in a Whitney catalog that you whack with a quick hammer blow. I've been using one for over thirty years. They also are great for getting the stuck screws out of the aluminum side cases. I usually try to have replacement allen heads on hand though.

Impact drivers definitely work well, for their intended purpose - freeing frozen fasteners.

But working with everyday screws, using the correct JIS driver on your bike is really a joy - screws fit on the end properly, there is no slop or cam-out, loosening and tightening them is so much easier and less work. Once you try them, you won't ever go back.

I concur with WingAdmin, I have purchased a set and had them sent over as they seem to be scarce in Oz. Since I got them, I have been using them on a variety of projects, and they are joy to behold. Nothing like a positive grip on a + head. There is not much you can say about a screwdriver, but these work like a dream.

so did none of your bikes come with a tool kit? there is a set of screw drivers in it! but i can see that a stubby set would come in handy. 8-)

Rejuvenation of an old post for more recent members troubled during restoration of their Honda.

There is a reason why you find those screws are damaged.
