The only reason they’re so common is because of Henry Ford. Ford wanted Robertson screws, but Ford also wanted to make his own screws in-house. Robertson wouldn’t license them, Philips would, the rest is history. Robertson screws are much more common than Philips up in Canada (where they’re from).
Because Philips screws were supposed to cam out, to stop overtightening on airplanes.
Maybe we shouldn’t use Philips screws for non-aviation purposes.
I’ve read this was the justification after the fact.

Right but for aircraft we’ve got torque wrenches which can stop overtightening much more accurately.

Robbies are a different kind of pain due to metric and imperial sizing
? Is this sarcasm. Robertson’s aren’t imperial or metric, they are numbered
the other commenter was right, I was misremembering and had hex keys in mind
Yeah hex (Allen Key) heads are a pain for that, especially if they are cheap loose fitting heads, then you don’t know if you have they right key
It’s Allens that aren’t in arbitrary sizes but their actual dimensions and sold in metric and normal sizes.
