Some claim to have stripped Robertson screws but to be fair, the metal used and amount of torque the peson applies is the biggest reason for problems.
Phillips heads were supposed to solve the over torquing problem, but everyone didn’t listen to standard specifications and didn’t bother using them as they were meant to be made and used. The Philips head was supposed to slip once the correct torque was applied. Unfortunately, this positive benefit became a negative. With poor metals and a mismatched driver bit to screw head along with not using the screw head that was meant for the specified torque demands, the Phillips screw became known for stripping.
Trying to implement non overtorquing feature to the square bit and you will find how similar it will look to the Phillips head.
Right now, Torx is the best at not stripping, but good luck if the screw is overtorqued. Eventually, the cheap metal gives out with the screw head, or bit, snapping off.
This is a common misconception. Phillips was not supposed to solve over torquing. It was designed to allow higher torques, stop slipping and self centre. It was only really good at self centering.
A screw designed to stop it being over toqured is a terrible idea. The screw should be smaller to prevent if higher torque is needed. If over torque is an issue then reducing the power to the driver is a much better solutio (easily done in industrial setting Phillips was designed for). You can also reduce the size of the screwdriver supplied.
Honestly, I dont understand why everything isnt square drive.
its simple, and its a pretty strong design that resists camming out and rounding off.
