That's great,but it's only the bit.
If you don't have a slot in handle to take the bit,it means further expense.

You are right of course, but I assumed pretty much everyone has a hex driver of some description in their toolbox these days.

As I posted up thread I'd no idea there was a JIS head and I suspect the vast majority of cyclists outside of the trade don't either....


ah but had you extended your catchment to all two wheeled enthusiasts, you would without doubt have encountered more folk with intimate knowledge of 'the JIS cheesehead affliction'. For a very long time every Japanese motorcycle was held together with ruddy JIS screws and for a very long time you basically couldn't buy a tool that fitted them properly and would undo the blessed things (after a year or two). The 'essential items for motorcyclists' list used to include

a) an impact driver, as well as
b) a kit of nice caphead screws or standard hex head bolts to replace all the cheeseheads

If you didn't replace the screws early on in the machine's life, you would typically be unable to access anything easily later on.
The impact driver kits never came with the exact correct bits so I would grind them to an approximate fit, hammer them in, and hope for the best; they only had to work once but even that seemed a big ask.... :roll:

If you were to gather together every motorcyclist who suffered with these things you would fill Wembley several times over and if they were to vent their angst simultaneously, it might go down in history as 'The World's biggest primal scream'.... :shock: :shock:

cheers

I did indeed swap all "cheeseheads" for Allen key bolts on all my Japanese motorcycles(six in all).I used IIRC PH #3 screwdriver tapping the handle whilst turning at the same time,and yes they were a PITA,but can't remember ever failing to get one out :)
I also still have a long T handled PH#3 driver from that period of dysfunction

Just got my JIS bits 0,1,2,3 and 4.

I tried them in a front mech , yes they do fit ,then I tried them in a pozidrive i think fit better.

Most people seem to agree that it's actually jis, it's also a pretty decent screwdriver in its own right.

Looking at the Q&A on the page you have linked to, CRC state specifically that it is not JIS.

Oh no it's not ............. say's the reply from Whiggy.

Personally, I don't give a toss one way or another.
Campag don't use JIS but Shimano do, and my tools seem to work fine with both.

Just picked up some nick nacks from CRC so tossed in the SD2 out of curiosity to qualify for free postage. I can always pop it in the cutlery drawer and use it to pierce the film on microwave meals.

The head angle on the sd2 certainly looks more phillipino.

Combination of Phillips and Flat on Campag. Slightly different to Shimano, though I use the same PH2 or flat on them both.

Give me half an hour, and I'll take one off of each and photo them.

Here you go! :D

Shimano on the left.
Campag on the right.

Shimano is a bigger head and screws into plastic for grip.
Campag uses a stainless spring for grip.
