The hexalobular socket screw push, often referred to by the initial proprietary brand name Torx ( /ˈtɔːrks/) or by the alternative generic title star drive, takes advantage of a star-shaped recess from the fastener with 6 rounded details. it absolutely was intended to allow greater torque transfer from the driving force on the little bit when compared to other travel systems. The push was formulated in 1967[forty four] by Camcar Textron.

A combined slotted and Torx push screw was used in electronics producing, and is still used by some corporations. such as, Compaq, HP, and Hewlett Packard organization (HPE) use this type to combine the key benefits of Torx in manufacturing plus the commonality of flat push in subject restore situations.

The Mortorq drive, developed from the Phillips Screw enterprise, is often a format Employed in automotive[35] and aerospace applications. It is built to be a light-weight, lower-profile and superior-energy push, with comprehensive Get in touch with around the overall recess wing, cutting down risk of stripping.[36] This minimal recess was able to make a shorter head top in comparison with other screws at time of its development, which in turn lessened the weight of the generate sort. The Mortorq was click here originally created for aerospace programs.
