It wasn’t designed to strip when overtorqued. It’s a myth with no evidence. The original patent says nothing about it (I’ve read the whole patent), and later patents list it as post-hoc justification for a design fault.
Add it to the list of reasons to hate Henry Ford. When he needed a new screw standard to replace slotted screws in his factories, he went to Robertson first, but he wasn’t willing to sell production rights to Ford. His second choice, Phillips, took the offer. Phillips and similar cruciform screw heads (Pozidriv and JIS, both of which are superior to Phillips) proliferated globally because of this, and it would take a massive shift in the industry today to fully transition to Robertson or Torx.
Phillips strips because it was designed to. Literally. And I fucking hate it.
Slotted is a bitch unless you have the motor skills of a neurosurgeon.
All tamper screws are offensive to me on a religious/spiritual level.

Really? We were actually taught this in college but come to think of it I never did read the fucking patent.
Look, what’s important is we all seamlessly transition to Robertson screws….
(Honestly I’m convinced it’s just spite for Canada that we haven’t already)
