No, no they don’t. You mix up Philips and JIS, you WILL have a bad day.
Source: I’m an old toolmaker that has made some nice pocket change over the years drilling out stripped out JIS screws on motorcycle engines from owners that didn’t know the difference. A decent amount from repeat customers too…
Oh, I absolutely believe that a Philips driver would ruin just about any other type of screw, but I don’t think that’s what the video talks about—they suggest using JIS drivers with Philips screws. Have you also seen problems with that combination?
When I was a toolmaker, a large part of my day was often spent removing stripped fasteners that others had messed up. And yes, I have seen that done, JIS used in place of Philips. They do equal damage, equally as well, and equally as easily.
The largest problem with ANY fastener system is that users are too stupid, lazy, and cheap to:
Buy quality fasteners. Cheap, Cheerful Chinese fasteners can often come pre-damaged and are cheese soft, saving so much time. Properly made, more expensive fasteners will seldom cause you a problem. (And yes, the Chinese do make quality items. YOU just won’t pay for them)
Buy quality tools and be sure they fit your fasteners correctly. The dollar store ain’t selling quality anything, anywhere, in that store.
Inspect your tools for wear and damage. They are consumables. Toss them when damaged or worn out.
Use the right tool for the job. If you don’t have the right tool, go buy it. Don’t try and fudge it.
Maybe. The opposite isn’t really true in my experience. Pozi drivers work well enough on JIS heads but Philips drivers slip way too easily. The bad thing is that JIS looks like Phillips heads which probably is part of the reason for Phillips rep of slipping out.
Whoops, you’re right, I had my memory of the geometries mixed up.
There is this interesting video that suggests that JIS drivers (a Japanese standard) work pretty well for all cruciform heads.
No, no they don’t. You mix up Philips and JIS, you WILL have a bad day.
