Phillips Screws (actually JIS)

[grog]

Jeykey, looks like i might be wrong then. Hard to work it all out. My so called JIS bits really do work well. Ill leave it at that.

I reckon ours are Philips and not JIS ! Maybe if we had a bike from the 60´s/70´s they´d be JIS. I´m still not certain but after a lot of googling I come to think JIS is extint nowadays. Take a look at this article and especially the comments section where they talk about the srewdrivers manufacturers, Hozan and Vessel(https://www.webbikeworld.com/hozan-jis-screwdrivers-review/). I read a lot of stuff about this. Had a detailed look at the Japanese tool makers that used to make and sell JIS and found no reference to JIS.  I was looking to buy JIS but not any more. Always used Philps with no probelems.

I have JIS for my historic japanese bikes, but the best way to get them out of engines is with an impact driver with it's the supplied bits.
