JIS ( Japanese Industrial Standard ) screw drivers and screw driver bits were mentioned quite a while back, in the excellent post the Ferret created about tools needed for working on the CB1100. In a nutshell, all the screw heads we see on the CB that appear to be a Philips head, are actually JIS Cross Head. I knew about this from doing basic maintenance on Japanese motorcycles over the past 45+ years, but some Japanese bike owners dont know about it.
A Philips screw driver will work, but has a tendency to "cam" out of the JIS Cross Head screw, sometimes causing damage, "boogering", of the screw head. This is something to be avoided, particularly on the clutch and front brake master cylinder covers. Instead of a full size set of JIS screw drivers, I use a set of JIS bits to use with my Craftsman handle. Easy to segregate in a small zip lock bag, inexpensive, and taking very little space in my tool box.
One of the premium Japanese tool brands is Vessel, and the company goes way back. I have a hand impact bought new back in 1968, I still have it, and it works just as well now as when I bought it. For a very good explanation, written and picutres, of the difference between JIS Cross Head, and Philips, check this web site: http://revlimiter.net/blog/2014/09/the-j...ewdrivers/
I found that vesseltools.com has much better pricing than revlimiter.net. Vesseltools.com is JDV Products Inc., and is the U.S. distributor for Vessel. JDV carries a full line of Vessel JIS, including screw driver sets, individual screw drivers, screw driver bit sets, and hand impact driver bits.
No, LOL, I dont work for JDV. I hope this will help out any of the membership that did not know about JIS.
