Why do we still use these lame screws....high torque screws would be so nice.
options:
Update:
1. Philips were chosen because Robertson would not give Henry Ford exclusive rights, he also would not license the design to other manufactures so widespread adoption slowed.
2. Square drives are American clones of the Robertson but slightly different. The American version will cam out faster then the original Robertson. Another problem is making sure to use a square drive tip in a square drive screw and a robertson tip in a robertson screw. There difficult to tell apart.
3. Philips head were designed to cam out because people and machines would over tighten them and either break the screw or item being assembled.
