Robertson screws

Does anyone have a reference that specifies the actual dimensions of the square recess in a Robertson screw for the common sizes? (#0, #1, #2, etc) Thanks!

the Patent filing would be a good place to look

I dont know if they were EVER patented in the US but i know american patents are online

Dont forget there is a reason why there is a SQUARE RECESS and a ROBERTSON an that the are NOT the same.
