Ugh, except Pozidriv will still cam and tear up their own screws, and same with Phillips. That's the secret to this tidbit of information that is never included. They're both trash fasteners when used with a slightly different driver, but they're also trash even when used correctly.

Robertson for life. When I was young I had a job assembling furniture and that, along with a couple Allen socket fasteners, was the only thing we used. Phillips fasteners that came with assemblies went straight into metal recycling to hopefully get born again as something worthwhile. You can practically drive a Robertson head straight through the center of the Earth with the amount of torque it handles. Never have to waste time drilling pilot holes.

If I was made dictator for a day, I'd immediately outlaw Phillips and Pozidriv. Even flat head is better than those pieces of junk.

There are a lot of Phillips fasteners that will also fit a Robertson bit. Just try both with the same screw. It's ludicrous how instantly you'll realize the Robertson is better.
