The Better Screw: A Canadian Grip

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

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.

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...

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.
