    Use JIS (Japanese Industrial Standard) screwdriver and bits. If you own a Japanese automobile, motorcycle, etc., you better use them.

      I know what you mean. I have a few older Hondas and there is jis everywhere. I’m talking jis on the dash, jis on the cluster, jis on the sunvisor, seat track, sunroof… Jis on the gotdamnt headliner. The things are practically covered in jis.

      Phillips is identified, in muricuh, by just the cross pattern hole.

      JIS is a cross patterned hole, with a separate round indentation in one of the cross corners.

      They are very close to each other, but not exact, and can round eachother out.

      JIS is definitely a step up from Phillips, as long as you have the right bits and can tell them apart. I run into JIS a lot in bicycle maintenance. But neither of them hold a candle to metric hex. It’s really hard to strip a hex bit until you’re being a total idiot.

        I’ve done it. It was a grub screw - so the hex was entirely within the shaft - that was surrounded by loctite, and frankly I never had a chance to get it out. It went circular immediately, just with hand pressure. I ended up having to use a screw extractor.

        I was told this was a common problem on ARRMA vehicles and that I should get a more precise type of hex driver. They were expensive but I haven’t had the problem since.

          OK yeah that sucks. I’ve run into hex grubs screws before, but on brake levers which I’m pretty sure have to meet compliance stuff like ISO safety standards so the hardware was higher quality.

            Also though these are RC size, 5mm screws, so much easier to kill. Apparently the issue is most hex drivers are slightly undersized, and ARRMA like to loctite their axle grub screws to hell.
