Torx (pronounced "torks") developed by Camcar Textron, is the trademark for a type of screw head characterized by a 6-point star-shaped pattern. People unfamiliar with the trademark generally use the term star, as in star screwdriver or star bits. The generic name is hexalobular internal driving feature and is standardized by the International Organization for Standardization as ISO 10664. Torx Plus is an improved profile.
