Not pictured here is also ‘JIS’ or Japanese Industry Standard screws.
They are very similar to Philips, but they’re slightly deeper with sharper corners. They have less tendency to ‘cam-out’ and strip the screw head.
Supposedly the camming out thing is actually intentional design in Philips screws, to prevent screw guns from over torquing screws in early automotive/aircraft assembly lines; but there’s not actually evidence to support that according to Wikipedia.

Yeah I thought it was funny they got the JIS head shape but not the drive.

Until you try to drive one with a Philips because who the fuck outside of Japan has a JIS driver lying around, then they strip real easy. Ask me how I know.
Why, why, are there so many different cross-shaped screw drives?
Funnily enough, I only know about these because I’ve got one of I Fix-It’s screwdriver sets with 70 driver bits.
I got one of these too, and holy shit is it worth it. Great purchase. I love not having to wonder if I’m going to have the right screwdriver head (generally. Obviously, this thread has taught me that there’s like infinite more types)

I was wondering why there were two sets of what looked like Philips and went looking for info.

If I could just wave a magic wand and make it happen I would change all screw-type fasteners into Torx and just be done with these problems forever.
