You just made me walk out to the shop.Look how common Robertson's screws are in everyday usage:
Drywall screws are Phillips as they are meant to cam out before going right through the board. Why you been lying about being a tradesman all this time?For people who build shit it is.
It's all square and star these days.
Drywall screws are still phillips, but that's because drywallers are all potheads and they don't know any better.
