Phillips vs. Torx Plus
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
Phillips
Torx Plus
The Phillips drive (Type I cross recess) is a self-centering cruciform drive system invented by John P. Thompson and commercialized by Henry F. Phillips in the 1930s (ANSI Type I / ISO 4757). Engineered with curved flutes and intentional cam-out torque limiting, it revolutionized high-speed automotive and aircraft assembly.
Torx Plus is an advanced evolution of the hexalobular star drive introduced by Textron Fastening Systems in the 1990s. Featuring squarer, elliptical lobes and a true 0-degree drive angle, it increases torque transmission capacity by up to 35% and extends assembly tool bit life by up to 100% in industrial manufacturing.
