John Phillips was commissioned by Henry Ford to design a fastener that could not be over torqued. The original Model T used Robertson – square drive – screws. The metallurgy was not up to the arm strength of Ford employees, the heads of the screws were being snapped off. The Philips screwdriver will put out only so much torque into the fasteners before the bit will slip out.
