JIS screwdrivers are the japanese version of the phillips, When you use a phillips on one it dosent fit right snd you will most likely strip it out. I repair industrial electronics for a living and run into them daily

I have a set of Vessel screwdrivers for JIS screws and they are very high quality.

JIS screws are great if you have the right tools, as they don't cam out. Unlike Pozidriv, it's not obvious that a regular Phillips doesn't fit well in the slot. The screws are typically marked with a dot in one of the quadrants defined by the cross slot.

They are common on motorcycle carburetors, copiers, and electronic stuff.

I will confirm that Japanese philips are a bit different shaped that the US standard philips.

I also will confirm that I have yet to find any screwdriver, industrial or not, that is durable enough to be removed from my "all screwdrivers are a diposable tool" list.

They look like Frearson or Reed & Prince as well.

Here are some JIS standard screwdrivers:

No special marking on the screwdrivers?

Wera makes JIS bits, search turned up some at Chadstoolbox.

Maybe the suffix on the size marking, it says "P1-15" and "P2-15". Could the -15 bit mean JIS?

It actually equates to the length of the blade. :)

Vessel conforms with JIS 1122/1112 and JCIS 10-70 standards for their (+) screwdrivers.

Here's what a JCIS 10-70 (#0) blueprint looks like:

I did some research and it seems like JIS standard (+) screws without dimples do exist.

i work on canon and ricoh copiers. they're full of jis screws. everyone i work with uses the old green handled ames no.1 philips screwdrivers made in germany. the number one phillips screw driver, if you grind the tip off will fit the jis fastener on a copier. i don't know about other devices. i use a 5.5 magnetic nut driver when i can. only problem is these jerkoffs can't decide what type of fastener they want to use. some parts are assembled with pan head fasteners, some are put together with hex head fasteners.

i was looking at vessels web site, how do you know if a driver is a jis driver? they say p1 or p2, those are phillips drivers. it looks like they're all phillips drivers

In 1952, Vessel became the first screwdriver manufacture in Japan to be able to produce JIS standard screwdrivers.

They go from No.0 to No.4, but it's essentially the same as the P or PH designation.

All the decades of owning Japanese motorcycles, I've always known there are JIS phillips screws. I just never bother to get the correct JIS screw driver. Probably why I mess up so many screw heads.

Question for all the motorcycle experts out there ... Are ALL philips in a motorcycle JIS philips? I do not recall seeing the dimple on ALL philips heads. The real question is ... DO I now have to carry ANOTHER tool in my tool bag?

What if I use a JIS screw driver on an American philips head?

The screws that I've dealt with in the past had a dot on them that almost looks like a centerpunch mark.

I guess that a lot of people don't know what a PoziDriv "phillips" head is marked with either.

I had never heard of this kind of fastener before getting on this site. I have worked on Mikuni and Keihin carbs (VM and PWK), but never noticed anything too oddball. I will have to look more closely next time.

Nolan, what is a PoziDriv "phillips" head marked with? Thanks.

The Pozi looks like a small square drive super imposed with a regular Philips. I guess you can say it is sort of both square drive and Philips drive in one.

I am not sure if I can tell the difference between the regular Philips and the JIS Philips just by the profile. The JIS suppose to have a dimple on the face of the head.

Looks to be the Pozi have less chance to have the head rip off because it has more "meat" between the head and the shank of the screw.

My understanding so far is that a JIS standard screw may not neccessarily have a dimple on it. I may be wrong, but it appears as though there was no regulation set in place for a JIS-compliant manufacturer to place a dimple on the screw head.

What this means for us screw-turners is this: try to purchase a few different screwdrivers from American, European, and Japanese brands.
Each one may have slightly different profiles and one may fit better on the screw than the other brand, given that there could be variables in the profiles and manufacturing tolerances, both for the screwdriver and the screw. So, if you want to make sure you're using the appropriate screwdriver for a particular screw, own a few of the same size (especially Philips #2/PH2/P2), from different brands.

Last Sunday, I purchased two Vessel JIS-Type Phillips screwdrivers from "RJR Cool Tools". Here is the website link: http://www.rjrcooltools.com/index.cfm. "RJR Cool Tools" is a one man operation. The owner, Ross Wegryn-Jones, handles stocking, customer service, and shipment of product. To set up the purchase, I called the main number, 877-230-2085. Since it was Sunday, I was expecting to leave a message on the company's voicemail system. However, I spoke to the owner on his cell phone. On the website, he sells a Vessel P3 screwdriver by itself. However, the Vessel P1 screwdriver is only sold in one of two sets. The owner was willing to separately sell to me the Vessel "900" thick shank, P1 screwdriver. While I was on the phone with him, he modified one of the web pages and created a custom order for me. After ending the conversation with me, I was able to purchase both Vessel screwdrivers through his secure website.

I received the Vessel P1 and P3 screwdrivers on Wednesday via the United States Postal Service. The cost of the P1 and P3 screwdrivers was $8.00 and $12.00 respectively. The owner does not charge shipping for any products purchased on his website. The Vessel P1 screwdriver is available in both "thin" and "thick" shank styles. The "thin" shank has a model number of "910". The "thick" shank has a model number of "900".

In all, I am very satisfied with my purchase from "RJR Cool Tools". The owner went out of his way to create a custom website order for me (even on a Sunday :thumbup:). The shipping was fast (two days from Dimondale, MI to Cleveland, OH) and free. Both high quality screwdrivers have a grippy, rubber handle with knurling at the top of the shaft.

I've purchased from RJR as well, with a similar purchasing experience. He was easily able to implement a custom order through his website, to accommodate my wants.

I don't think there's too many screwdriver makers that incorporate knurling at the base of the shaft like Vessel and some other Japanese makers do. I find it handy for the smaller sizes like PH0 and precision flat blades.

Here's a few that I got:

I also got the extra-long Megadora; no picture though.

Superautobacs,

Since you own a Megadora screwdriver, which handle style (Megadora or Soft Grip) do you like better and why?


Thanks,

Dave
