Japanese Industrial Standard Screwdrivers

afazz · Dec 25, 2009

Great! I just ordered the set of two #2 and the #1-#00 set. I've needed (read:wanted) a set of these for a while. It's amazing how many items have the "dimpled phillips" once you know what to look for. Automotive stereo equipment and SMC pneumatic components just to name a few.

dede2897234 · Dec 31, 2009

Besides Hozan and Vessel, which other Japanese hand tool manufacturers produce JIS screwdrivers?

(Note: On Hozan and Vessel's official websites, the terms "Japanese Industrial Standard" and "JIS" are not used to describe each of their screwdriver offerings. However, the U.S. tool resellers that carry Hozan and Vessel screwdrivers mention the above terms.)

Are the cross recess screwdrivers manufactured by Kyoto Tool Company (Nepros) true JIS screwdrivers?

Here is a Nepros webpage talking about their screwdrivers: www.nepros.net/tools/t_features/screwdrivers.html.

Thanks,

Dave

Difficult to say. On the webpage they say the red cap screwdrivers are Phillips. On the other hand they mark them only "P1" ,"P2" etc. and not "PH1" , "PH2" etc. for Phillips. The Japanese website gives no more info (at least i can`t find/read any....)

ps:
Did you ever try a JIS cross head screwdriver with a Phillips screw ??

more screwdriver manufacturers
www.anextool.co.jp www.tokoma.co.jp http://www.niigata-honmono.jp/wise/ www.sunflag.co.jp http://ktc.jp/

It seems that many of them only offer "cross head" drivers , not specified if JIS, PH or PZ, they just show the "cross head" symbol with size number #1 #2 etc. or P1 ,P2 etc. so i guess that they`re JIS drivers since most of the companies will principally sell their tools on the japanese market and asian market so i guess that they`re JIS drivers and PH and also PZ seem to be unknown.
But maybe the JIS will fit the PH and then they automatically fit PZ too.

Here is a info about screwdrivers direct from the japanese hand tool mfr. organisation but in japanese...

Monte,

Thanks for your opinion and links to the Japanese screwdriver manufacturers. I own a Nepros #2 Phillips screwdriver (model # ND2P-2). I also own a Wiha MicroFinish Extra Heavy Duty Phillips screwdriver. The Nepros fits Phillips screws more completely than the Wiha. The Wiha's screwdriver tip sticks more out of a Phillips screw than the Nepros. As a result, the Wiha is more prone to cam-out than the Nepros.

Monte,

I just finished searching through the various webpages of the Japanese screwdriver manufacturers you mentioned in the previous thread posting. Only Anex and Sunflag mention the term "Japanese Industrial Standard" or "JIS". However, only Sunflag mentions "JIS" when describing each of their screwdriver offerings.

Here is a link to the Anex webpage mentioning "JIS" under the left side heading "Industrial Quality": http://www.anextool.co.jp/technology/. I used Google Toolbar to translate the Japanese webpage to English.

Here is a link to the Sunflag model #'s 665, 666, and 888 screwdrivers mentioning the JIS tip: http://www.sunflag.co.jp/products/product.php?gr1=1&gr2=1&img=666&title=ハイソフトドライバー.

It seems like Anex screwdrivers are only available in Japan. Sunflag screwdrivers are available from various online Australian tool resellers and an eBay Australia tool vendor. I am going to investigate purchasing several Sunflag screwdrivers from Australia.

To be continued... :bounce:

I hope you update us. I would go in on that deal with you....maybe. depending on price and other things.

Monte and M900,

Yesterday, I contacted Sunflag Japan about their screwdrivers. I spoke to H. Shimizu via e-mail. His e-mail address is the following: [email protected].

Shimizu informed me that all their cross recess screwdrivers have JIS tips. In addition, Sunflag does not have any tool distributors or resellers selling their product line in the United States or Canada. Sunflag tools are only available in Asia, United Arab Emirates, Saudi Arabia, and Kuwait.

Before contacting Sunflag yesterday, I located an Australian tool reseller called "Just Tools" that carries a nice selection of their tools. Here is the webpage on the "Just Tools" website showing its selection of Sunflag tool products: http://www.justtools.com.au/category115_1.htm.

I plan on contacting "Just Tools" in Australia in early February about purchasing some Sunflag cross recess and slotted screwdrivers. I will post my purchase experience here after I receive the screwdrivers.

I'm late to the party...............

I have a simple question......

When using a Craftsman (G-D forbid) screwdriver to try and remove some (philipps apearing) screws from a 87' Honda carb, I was having trouble and making a mess out of the screw.

Might these screws be of the JIS variety and therefore the Craftsman #2 Phillips was not correct.

Is there any rule of thumb, for knowing when I'm not dealing with a Phillips ??

Thanks for the education

M900 · Jan 8, 2010

Ive only "heard" that they were used a lot on carbs. Im not sure though as Ive never worked on a carb.

I know of no rules to differentiate.

I am sure you encountered JIS screws when working on a 1987 Honda carburetor. If you go to post #15 on page 1 of this thread posting, "Superautobacs" posts pictures of JIS screws.

dede2897234 · Feb 20, 2010

I received the Sunflag cross recess screwdrivers today from Australia.

In the below pictures, I compared the profiles of the Vessel and Nepros cross recess tips.

As is shown in the last picture, the bottom tapering on the tips do not end at the same point on the Vessel and Nepros #2 screwdrivers.

Here is a comparison of the #3 screwdriver tips of the Wiha Microfinish, Vessel Megadora, and the Sunflag "215" screwdrivers:

As can be seen in the second last picture, both the Wiha and Vessel start to taper upwards on the tips at the same point. The Sunflag screwdriver starts at a lower position to taper upwards on its tip than the other two. In the last picture, the taper at the bottom of the tips end at the same point on the Wiha and the Sunflag. The Vessel tapers to the bottom of the tip at a lower position than the other two screwdrivers.

Through a Google search, I found an individual's comments stated in the following radio controlled helicopter forum mentioning that the cross recess tips on the Vessel Megadora screwdrivers are not JIS but conform to ISO standards:
http://rc.runryder.com/helicopter/t256687p1/. He also said that the other cross recess screwdriver models in Vessel's lineup conform to JIS standards. Two examples are Vessel's "600" and "620" series JIS screwdrivers (picture borrowed from "superautobacs"):

http://farm3.static.flickr.com/2508/3685793249_122de76396_b.jpg

Does anyone know the true differences between the JIS and ISO cross recess standards?

Does anyone know which specific numbered standard (ISO or DIN) the Wiha MicroFinish Phillips drivers conform to?

3/8/2010 Update:

I purchased last week the cross recess #1 (model ND2P-1) and #3 (model ND2P-3)screwdrivers directly from Nepros (www.nepros.net). I learned today from Eri Inoue, a company representative, that their cross recess screwdrivers do not conform to the JIS standard:

<< Well, regarding Nepros Phillips Screwdrivers, they don’t meet the JIS standard.
If we adjust the products to a standard, they will be awkward to use. JIS standard have so many regulations.

As for the standard [ex: DIN/ISO 5260, DIN/ISO 8764], the Nepros Phillips screwdrivers do not meet any of standards. We made them as our own standard which we designed for ease of use. >>

Thanks,

Dave

The Vessel Megadora #2 screwdriver does not have a JIS tip.

Very nice write-up. I've been researching JIS drivers lately, the RJR Tools website does have a disclaimer that the Vessel screwdrivers aren't true JIS, but claims they're "good enough." http://www.rjrcooltools.com/vessel.cfm

Ames Supply has JIS drivers here: http://www.amessupply.com/products1.cfm?aid=1&cid=D&sid=DE&fid=1404070 Not exactly the sexiest handle design, and it doesn't look like #3 size is available, but priced reasonably.

I believe the link below implies Snap-on screwdrivers meet Japanese Industrial Standard (JIS 4633B-3/1991).

http://www.katun.com/products/toolsjis.html

"Katun provides Snap-on screwdrivers (and Katun-brand screwdrivers, manufactured by Snap-on) that meet all Japanese Phillips specifications. Snap-on screwdriver tips are also vapor-blasted for maximum grip within the screw slot."

Also on page 21,

bentt · Feb 20, 2010

Of interest, RJR Cool Tools describes their Vessel bit drivers as DIN 5260 (JIS-Type) while Ames' states their screwdrivers are compliant with Japanese industrial standard JIS 4633B-3/1991 and DIN/ISO standard 5260.

Mike_47,

I am glad to hear that you liked my write-up.

Before I purchased the Vessel screwdrivers from RJR Cool Tools, I read the disclaimer on the web page you linked to above. The owner of RJR Cool Tools states that the Vessel screwdrivers conform to the JIS standard and the 1/4" bits conform to the DIN 5260 standard (JIS type). However, I feel that RJR Cool Tools should apply that disclaimer to the Vessel Megadora screwdrivers as well. If you re-read my write-up, you will notice differences in the cross recess profiles of the Vessel Megadora and Nepros #2 screwdrivers.

As far as the JIS screwdrivers available from Ames Supply, I would be cautious about buying from them. Here is a link to a post (see #14) on the Honda GLI800 Goldwing Forum dated 10/29/2009:

A more available and relatively economical option for JIS screwdrivers is PB Swiss. According to this thread (post #1) on the Practical Machinist website, all PB Swiss Phillips drivers should work on JIS fasteners:
http://www.practicalmachinist.com/vb/general-archive/more-phillips-jis-screwdrivers-74364/.

Since the PB Swiss Phillips screwdrivers work with both ISO/DIN and JIS (like the Vessel Megadora screwdrivers), it will turn JIS fasteners without damage.

Mike_47,

The Vessel Megadora screwdrivers will work with fasteners with a JIS cross recess head. However, the Vessel blade tip will not make maximum contact with the fastener head and not provide maximum torque to tighten or loosen the fastener.

FWIW, the green screwdrivers offered by Ames is made by "SKG" in Germany.

The ISO was established in 1947, in an effort to create a global standard for many things, including the vast family of screws, bolts, nuts, washers, and screwdrivers (I don't know when standards were set in place for those things though).

The JIS standard was established in 1949, and again, I don't know when standards were set in place for screwdrivers and the like. Apparently, over the years, JIS has been moving towards conforming with the international standards (ISO). Hence, JIS has ammended their standards so that it's compatible with/equivalent to the ISO standards.

Wiha MicroFinish Phillips are made to conform to ISO 8764 standards.

Look at the JSA (Japan Standards Association) website link and you'll find that the standard used for cross-recessed screwdrivers conforming to JIS B 4633 is equivalent to ISO 8764-2:1992 and ISO/DIS 8764-1:1996--the same standard as the Wiha MicroFinish.

dede2897234 · Feb 22, 2010

Superautobacs,

Thanks for all the wonderful information!

If you look at my write-up on page 3 (post # 53) of this thread, you will notice differences on the cross recess tips of the Wiha MicroFinish and Sunflag #3 cross recess screwdrivers.

Since those differences exist, how could the JIS B 4633 standard (Sunflag model "215" #3 screwdriver) be equivalent to the ISO/DIN 8764-1:1996 standard (Wiha MicroFinish #3 screwdriver)?

Thanks,

Dave

Monte · Feb 22, 2010

If you look at the link superautobacs provided this is written on the page:

Corresponding International Standards ISO 8764-2:1992 (MOD) Explanation of Equivalency
ISO/DIS 8764-1:1996 (MOD)

if you click on "Explanation of Equivalency"
this text appears with explanation:

IDT: "identical"
MOD: "modified"
NEQ: "not equivalent"

"modified"
JIS is modified in relation to the International Standard if technical deviations, which are permitted, are clearly identified and explained. JIS reflects the structure of the International Standard, but changes in structure are permitted provided that the altered structure permits easy comparison of the content of the two standards. Modified standards also include the changes permitted under identical correspondence.

So to my (limited english) understanding the JIS norm is a modified ISO standard and not identical (otherwise not MOD would be stated but IDT) but also not complete different (NEQ)

Somebody has 5460 yen ???

Looking at those pictures, I can see a clear difference, and I'm sure there are other differences in the dimensions of the tips that are hard to portray on a two-dimensional photograph.

Regarding your view that there's a discrepancy in the standards between the Vessel/Wiha and the Sunflag screwdrivers can be explained by asking ourselves a few things:

First, we should look into when the screwdriver was manufactured. Perhaps it was made some time ago, when the JIS standard for cross-recessed screwdrivers did not closely mirror the ISO standard as it does today? Maybe it is a recent production, but Sunflag chose to produce theirs in accordance to an older standard that suits the older JIS screws found on older equipment?

The current JIS standard for cross-recessed screwdrivers and the corresponding screw-head profiles are in consistent with ISO standards, and thus, we find Vessel Megadora's profiles to be close to/same as a Wiha, PB Swiss, or any other manufacturer that produces a ISO/DIN 8764-1:1996 or equivalent Phillips screwdriver.

We know that standards change from time to time. With that in mind, we also have to wonder how much the standards have changed over the time for Phillips head screwdrivers under the ISO standard.

Kinda gets complicated.

Why would Nepros not manufacture their cross recess screwdrivers to a DIN/ISO standard and use their "own standard"?

Have you heard of other tool companies manufacturer their screwdrivers to their "own standard"?

Are Nepros's reasons for not manufacturing their screwdrivers to a recognized standard legitimate as far as making the tool easier to use and compatible with a greater variety of cross recess screws?

Thanks,

Dave

superautobacs · Mar 8, 2010

Dave,

It's interesting to learn that Nepros' cross-recess screwdriver were not designed and manufactured in accordance with JIS or any other international standard. I wouldn't say that's a bad thing. Afterall, like most other regulations and standards, they are simply minimum standards. They are standards that can be used as a model and the basis for a design.

Nepros is KTC's premium line, and they poured in a lot of R&D into developing their line of products. I guess their screwdrivers are no different. Instead of following any given standard, they chose to develop their own unique(?) profile.

I haven't heard of any other screwdriver manufacturers making products under their own standards, but I've certainly heard it with other hand tool manufacturers.

Monte · Mar 8, 2010

Hi Dave
I don`t know if someone else makes their screwdrivers to their own standards, regarding the german manufacturers i only know what i wrote you in the last PM, the result was that IIRC all of them produce to the effective ISO standards. I think it will be difficult to sell something to industrial customers if the tool is not produced to DIN/ISO standards because it is demanded by the customer or sometimes the tool is considered unsafe if DIN/ISO standards are not fulfilled so the customer won`t buy it no matter how good the product is. I case of screwdrivers and bits there are own developments like the "PHZ" drivers which work with for example PH 2 and PZ 2 screws or the PHZ1/2/3 which also work with different sizes. So i guess Nepros developed their own tip-profile so you can use PH, PZ and JIS screws with the same screwdriver. The question is if not a PH screwdriver fits better in a PH screw than a Nepros driver. This is a test which you could do with your Nepros driver and a similar sized PH and PZ driver and then look which "cam-out" first.

mkirkpatrick · Mar 10, 2010

This may be a dumb question, :dunno:

but can a frearson screwdriver be used on a JIS head without hashing the head out. I used a philips on a distributor rotor and messed it up pretty good. I buddy of mine that turned wrenches for a living got it out for me with a frearson. I looked at the article on industructables and honestly the heads look the same to me. :shocking:

I purchased from The Wood Works in Sydney, Australia last month the model "888" sizes #2 and #3 cross recess screwdrivers.

When the package arrived last week, I visually compared the model "888" and the model "215-P" size #3 cross recess screwdrivers. I noticed design differences in the two.

I attached to this thead posting 4 pictures of these 2 screwdrivers to demonstrate the below comparisons.

As can be seen in the below attachment, the model "888" has recesses that are longer and narrower than on the model "215-P". In other words, the recesses on the model "215-P" are wider than on the model "888".

As can be seen in the below attachment, the crosses begin to taper earlier on the model "215-P" than on the model "888". As a result, the tapered portions of the crosses are longer on the model "215-P" than on the model "888".

After reviewing the last 2 pictures, it did not make sense to me that the cross recess tips of the models "888" and "215-P" appear different and yet both conform to the JIS B 4633 Standard.

I contacted Mr. Shimizu of Sunflag in Japan Monday to please research which JIS standards are associated with the models "888" and "215-P" cross recess screwdrivers.

The below quotes are his responses to my 2 e-mails:

<< Both 888 and 215-P are produced in our factory in accordance
with same JIS standard [JIS B 4633]. >>

<< One shank is round and the other is square.
So, finish of the production naturally looks different.

Depth and width of the each recess are different because shape of
shank is different.
The important thing is angle of recess.
If it's different, it cannot be fitted with #3 screw.

Please insert each screwdrivers to #3 screw so that you can
find that points of each screwdrivers fits to screw in the same
way or feeling.

Thank you for your kind attention.

MKirkpatrick,

I did some research on using a Frearson screwdriver on a JIS fastener on Google last week. A number of individuals in online forum postings, like your buddy, have used a Frearson to loosen a damaged JIS fastener head. If you would like to purchase a Frearson (or Reed & Prince), Snap-on sells them here:
http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=14711&group_ID=722&store=snapon-store&dir=catalog.

Snap-on has those Frearson screwdriver tips in stock. I purchased 2 of them along with other items on Monday.

Mike,

I would not use the Snap-on Frearson screwdriver bits in an impact driver. The screwdriver bits are not impact grade.

The Frearson fastener head is a perfect cross. The JIS fastener head is nearly a perfect cross. I do not believe that using a Frearson screwdriver bit will damage a JIS fastener. I have read that you can interchange a Frearson screwdriver bit for a JIS screwdriver bit.

I am a firm believer in using the right tool for the job. RJR Cool Tools sells Vessel JIS-type (ISO/DIN 5260; the closest to the JIS standard) screwdrivers and screwdriver bits at a reasonable price. Here is the link:
http://www.rjrcooltools.com/shop_item_detail.cfm?subcat_ID=138.
I have purchased from him earlier this year the Vessel screwdrivers and he provides great customer service. Another bonus is that he does not charge for shipping.

If you would like to purchase true JIS screwdrivers and have money to burn :thumbup:

, it is going to cost you! I purchased a #2 and #3 Sunflag (Japanese) cross recess screwdrivers for $30 a piece (price includes shipping) from "The Tool Works" in Sydney, Australia. Here is the link:

Dave,

My sister in law has friends in Japan, I told her what I was looking for, she made a couple phone calls so I will see what that produces. I was looking at the screwdrivers on the link before. I know the snap on aren't impact grade and are 1/4 and not 5/16 will still keep looking for an impact one. I know that when my friend removed the one I screwed up from the rotor he used a impact(hammer screwdriver not air gun) and a SO bit.

Figured i would update this thread with another option (unless i missed it somewhere) for the Vessel drivers.

I took a chance on the #1-#3 set, and they are Vessel. I haven't had a lot of opportunity so far to try them out, but they seem to be good quality pieces.

I will probably order the smaller set next week and see what they send.
