Where to buy JIS screwdrivers in Singapore?

[MiddleAgedBiker]

Does anyone know any shops that sell JIS (Japanese Industrial Standard) screwdrivers in Singapore?

[Phang]

I have 2 sets of screwdriver, one from European brand and the other from Japanese. I am not sure my Japanese set is JIS but those cross head screwdriver in the Japanese set tends to fit the JIS cross head screw better than my European set.

 

For example, for #2 JIS cross head screw (I’m sure you know how to tell it is a JIS cross head), my #2 Japanese cross head screwdriver will fit perfectly while #2 Phillips will feel loose even though the tips of both screwdriver look the same to me

 

On the other hand, the European set screwdrivers fit better to the Phillips screws on my European bike… funny hor

 

Sorry for unable to give you an answer

Hi Phang, thanks for the review. Yes I heard they fit much better, no wonder my Phillips strip all the time. May I know where you bought yours?

[Phang]

The brand of my screwdrivers set is KTC, I bought them from Wing Poh many years ago while there were still at Balestier. They have moved to the building behind LTA at Sin Min now.

 

They don’t have a sales counter, it is an office. Tell the staff who sit nearest to the door that you want to buy screwdriver and he/she will serve you even though you only buy one piece. Yes, they accept cash payment.

 

Be warned, it is a candy shop for DIYers

Ok, you guys piqued my interest on wat the hell a JIS screwdriver is. I did some goggle researching and thought i should share this link so that others who are as ignorant as myself who do not know the difference will understand.

Look at post #7.

 

Explains why a phlips head wont sit nicely into JIS screw.

 

Interesting eh? I never knew. I gotta thank TS for making me aware of such differemces

[Phang]

Which one is JIS and which one is Phillips? Hehe...

I used to hear mechs complaining about Japanese using lousy screws on carburettors as they always strip the head of those screws. They like to replace those screws with inner hex (aka allen) screws.

 

In fact, they’re using the wrong screwdriver

 

If you take those older MRT train with coaches built by Kawasaki Heavy Industry, those exposed cross head screw in the cabin are all JIS screws.

Maybe not screw of the mechanical kind, but 'biological' kind, if u get wat i mean. Haha.

 

Jokes aside, the pic u attached, all the screws are Phillips, am i right? I'm guessing that based on purely the diagram posted on the link that i pasted above. If i'm wrong, pls enlighten me. I also read that JIS screws are identified by a dimple at the corner.

If its not too much or troublesome to ask, can i request u post a pic of a JIS screw and a Phillips screw side by side for comparison? And also perhaps the screwdriver head of both types as well?

 

Sorry if i'm going slightly off topic by asking so many qns. Most of us are riding Japanese bikes and i think its good to know what the differences are if we want to DIY ourselves. Dun want to end up with a worn out screw head especially when adjusting our engine idling speed. (Happened to a friend of mine)

If u are an amateur, i'm a complete novice and i just want to learn more. Hehe.

Yes, the dimple is a good way of identifying a JIS cross head screw but not always correct. I have came across JIS cross head without dimple on my bike too.

 

The smaller screws in the carburetor photo I posted earlier are JIS screw and the bigger ones are Phillips, you can see the dimple on the JIS clearly. Without the dimple, they are all look the same to me

Honestly, I can’t tell whether it is a JIS or not by looking at the screw or screwdriver. When I work on my bike, I always carry 2 sets of screwdrivers. When one doesn’t fit and sloppiness felt, the other set will fit.

 

Otherwise, I will pull out our local mech’s all time favorite mighty tool – The impact driver! It will chew out whatever **** it hits

Thanks for the links Phang. I'll check them out.

 

First I thought my technique was crappy, that's why I stripped the screws.

Then I thought my drivers were crappy, that's why I stripped the screws.

Finally I realized it was the wrong tool for the job all along. lol...

 

I read that all Japanese OEM manufacturers use JIS screws on their products. So even those without the dimple are also JIS spec'ed, but I don't know how accurate this is. I think for the drivers, the bits are more angled than regular phillips.

 

I'm also told that using a normal Phillips driver on a JIS screw will cause it to strip, but using a JIS on a normal phillips screw is ok.

 

Some folks who use high quality normal drivers like Snap-On also report that it works ok on JIS fasterners.

I think the poster is mistaken. The picture he posted of the supposed JIS is a Reed and Prince type screw I think, not a JIS.

 

A JIS screw doesn't really look much different from a Phillips, but the Japs make it to their own specs. The differences are in the internal angles of the slot, I don't think you can tell externally except for the dot on the head. I think they say their tolerances are tighter than the European specs, or maybe it's different, I'm not sure.

 

There are actually 4 different types of screws that look similar to each other, but to our untrained eyes they all look like Phillips.

 

There's regular Phillips, JIS Phillips, Reed and Prince and Posidriv. They all require different screwdrivers.

These are some of my screwdrivers.

 

The 3 screwdrivers at the bottom of the photo are specially made for carburetor maintenance and tuning

Those are KTCs. You are right, they are more like a toy than tool

[ezzyoiler]

screw those who think the world will follow them by introducing their proprietary tools..

 

obviously they dont believe in standardisation...why need so many types...where one will do.

 

just like the mobile hp battery and their battery chargers.....

the phone manufacturers just want you to throw away your current batteries and chargers...and you need to buy the latest battery/charges...when you change phones...

 

but the eu is going to change that...stardardise batteries/charger....hope they succeed.

 

so for bikers..if you own a american and a jap bike ..both or one after another.....during your lifetime..you may end up with 2 sets of fps/mks tools..
