The Better Screw: A Canadian Grip
In 1908, Canadian P. L. Robertson invented the square-socketed screw to prevent 'cam-out'—the slipping that plagues other screw types. This superior grip made it highly efficient. While the Phillips head became more common globally, the Robertson screw remains widely preferred in Canadian construction and manufacturing for its reliability. #Canada #Innovation #Invention #Tools

@Canadian_Eh Oh my god, if I find out who is putting slotted screws in things in 2026 I will end them 🤬.
Philips are bad enough but holy hell, stop with the slotted already!
I *rarely* if ever have stripped Robertson screws.

More than once I have rounded out the screw (or found it has rounded out) and wondered if a triangle shape would have worked better.

@javensbukan @Canadian_Eh Uhm, hex keys are not a thing over there? Don't you have IKEAs?

Interesting thought.
The three sharper points of the driver would be a bit (so to speak) less robust than four pointed corners, which perhaps Robertson thought about. On the other hand, the fastener itself might well have greater strip resistance. Someone must have experimented by now...

@hennichodernich @Canadian_Eh We do! And those are pretty great tbh. Though they're rarely used in building and general house construction.
Case and point, every single lightswitch panel and outlet in my house has these stupid slotted screws and I hate them.

The three points of the driver could be a bit rounded. The three (relatively) broad faces would provide enough contact to move the screw after losing a bit of meat on the corners.

@javensbukan @hennichodernich Ouch. I know that pain.

@Canadian_Eh @javensbukan @hennichodernich It’s interesting as I think all the front facing screws on light switches are slotted. I have to wonder if it’s a cosmetic thing.

@Chigaze @Canadian_Eh @hennichodernich Yeah that's my thought too. Maybe because you can make slotted very small and shallow?
