Looks like the next guys problem.

Tool steel screw and mild steel bit.

Is that how drillbits are born?

Quit screwing around! You all screw around too much!

better screws are torx

Have you been to a lot of hardware stores with different grades of every of the 257 different types and sizes and thicknesses they carry?

I've read this was the justification after the fact.

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).

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

Came here to say this. The correct size and depth bit on a Phillips is a thing of beauty and grace. If you get it the slightest bit wrong (pun yes) God help you and your offspring to 7 generations.

Especially when a similar size will feel like it fits pretty well, until it cams out at much less torque than it should.

I've picked up a set of anti-slip bits, they are pretty much ribbed so they bite into the screws just enough to cam out a lot less often. Works better than I hoped for maybe $7 for 5 bits in different lengths.

As someone who has spent far more time than I want to think about removing screws and bolts that other people fucked, Robertson is the second most popular fastener to get brought to me with Torx in hot pursuit.

Philips head screws that are messed up come in two types. Soft cheese metal versions and the insidious Japanese style that are just ever sooo slightly different and require their own special driver. And most of you can't tell the difference or even care.

Plus, Y'all buy cheap ass "turn screws" as the British used to call them. When you buy dollar store quality tools you deserve what you get and I don't feel sorry for you.

There's like 3 use cases for slot heads, and there they're worth their weight in gold. Everywhere else however? Fuck 'em.

Slot heads never wear out.

At this point you're just asking for a yo mamma joke

Why?
Robertson is clearly superior. You're not going to strip that, and it holds onto the screw better.

Robertson is great though

And yes, I used a Phillips screwdriver in JIS and vice versa multiple times.

That's totally fine actually
