Jis?

What is the proper screwdriver for these screws? I have ground a #1 phillips a little on the end but it doesn't seem to fit right. I have some smaller jeweler type screwdrivers that seem to fit better but flimsy handles that I can't get much downward force on. Are these screws JIS? If so, how do you specify so I can get one that is a good fit?? Thanks!

I did the same thing with a #1 Phillips and it does seem to fit fine on small JIS screws like the B-screws and limit screws on Shimano derailleurs. The screw you show seems to be bigger and perhaps a #2 Phillips would be a better starting point.

#2 JIS or now CrossTip as those things are getting standardized. Pretty much I cannot think of a use for an actual Phillips screwdriver when a JIS or now CrossTip does the job better on Phillips screws from what I have observed using JIS.

Getting good tools will generally prevent issues and up the enjoyment.

I'll second this recommendation for Hozan JIS screwdrivers.

FWIW: I thought I remembered getting my set from Amazon, so I checked. Amazon still carries them - and the price is somewhat better than this eBay source if you have Prime or your order has a subtotal of >$25. (I find the latter is always pretty easy to manage if necessary. )

I've found that it's a good idea to check Amazon too if you find something in current production you want/need on eBay. For items in current production, Amazon is often a possible second source if the eBay vendor is out of stock. And sometimes Amazon is cheaper.

Thanks all! I just ordered the #2 JIS Hozan from Amazon. I made this order before the kit was suggested but I think the 2 will do most of what I want. Looking forward to trying it.

I wasn't really shopping for someone, just pointing out their availability.

i have a MAC #2 JIS.. "kind of a 1.5 Phillips!" as the Driver described it... Bought for use on Kubota Tractors and Mowers, at the time...I've been abusing it's superior design qualities for about 20 years now... it's about due for a new blade... still kicks butt on a Std. Phillips.

Understand. I was just (1) agreeing with your recommendation regarding Hozan JIS screwdrivers, and (2) pointing out that Amazon sometimes has a better deal than eBay on current production items.

It's a JIS 1 most probably. JIS 2 is often too big to nicely fit those particular screws (Shimano flat-bar shifter cover screws).

A set of decent JIS screwdrivers (Wera, Vessel or Hozan) should help (size 1 and 2 cover most bicycle-related work). They are all sold as "Phillips," but the listed brands make their Phillips work well with "Japanese" screws.

My detailed explanation on Phillips vs JIS (vs Pozidriv).

Um, no. I always use the correct tool for the job. Itís pretty funny you think you know what tools my bike requires.

Run along, now.
