HIOS Inc. has specialized in the manufacture of screw tightening equipment since its inauguration in 1970, and we continue to develop our business today while considering the global environment and improving overall work efficiency.
From a historical perspective, HIOSelectric current control M series acted as the prototype for the start of air screwdrivers during Japan’s post-war economic boom. This gave rise to the development of HIOSCL series with attached mechanical clutch, offering compact size and low voltage design, ensuring accurate and safe screw tightening.
HIOS VZ series of AC screwdrivers traces its origins to the field of precision equipment assembly, but this range of products remains an industry leader in Japan to this day.
