JIS Cross vs. Torx Plus
Comparing 2 standards across 13 specifications. 13 key differences identified.
JIS B 1012 is a Japanese Industrial Standard cruciform screw drive commonly found on Japanese motorcycles (Honda, Yamaha, Kawasaki, Suzuki), cameras, and consumer electronics. Visually similar to Phillips, it features a shallower center pit and parallel 90-degree cross-wings engineered not to cam out, which easily strip when turned with standard Phillips screwdrivers.
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.
