While this style of drive system allows high torque transmission it is prone to early failure. When rotational pressure is applied to the tool this is transferred to the points of contact between the hex tool and the drive socket in the screw head. This localised pressure tends to round off the tool resulting in damage to both the tool and the fastening.
Torx developed in 1967 by Camcar Textron, is a trademarked type of screw drive characterized by a 6-point star-shaped pattern. A popular generic name for the drive is star, as in star screwdriver or star bits. T
