Review on 🧰 Premium Sunflag +1 +2 +3 JIS Screwdrivers: Made in Japan with Perfect Grip by Sean Skinner

I bought these JIS screwdrivers specifically to work with my bikes. From what I've read online, shifters made in Japan use JIS type adjustment screws - screws that set the lower and upper limits of travel when shifting. " Phillips head screwdriver. I didn't know there was a JIS standard until I came across an article about Japanese shifters and JIS screws. I've used these JIS screwdrivers to adjust the front and rear derailleurs on all of my family's bikes Works great - won't slip or break the screw head The price is very good too - lower than most JIS screwdrivers on the market These JIS screwdrivers are also a must have if you own an Asian made vehicle and with it work.
