Two pages.
One photo of a screwdriver in a dearaileur limit screw sansa hands.
One flounce.
Three "i have been in theindustry"
well a major manufacturer ( vessel )says they don't make them any more and haven't for a long time
I know it'll still cause an argument 😆
I do have one. It fits perfectly in shimano mech limit screws like no other screwdriver I've tried. I could have got by without but I bought one because I was interested and they weren't expensive
yes I've seen the pics but seems like many decent modern screwdrivers negate any JIS specific tools
Quite possibly I could have bought any decent Philips and been equally happy but I don't think the ones I have are that rubbish 😕
If you want true screwdriver bullshit then have a look at a new type Campag rear mech.. They've put both Pozi and Philips adjustment screws on the same mech. No words. Utter wtf.
just buy 50 stainless allen head screws and replace every limit screw with something that works M4 x12mm as far as I remember - please check before ordering !
I have been using a screwdriver(No2 philips/JIS) made by snap-on for Katun everyday for several years and have tried other snap-on screwdrivers and there is a huge difference.The katun/Snap-on fits perfectly whereas the snap-on No2 philips does not and cams out. The screws are mostly marked as JIS, I have used many other No2 Philips over the years.
Which others fit well is a bit random, standard Snap-on are useless but yet I have used a £1 cheapie which fitted like a dream but long term use would be useless are it would wear very quickly.
