HIOS Inc. has been specializing in manufacturing screw tightening equipment since its establishment in 1970, and we continue to develop our business to this day while considering the global environment and improving overall work efficiency.
Historically, our M series of electric drive motors served as the prototype for the beginning of pneumatic screwdrivers during Japan's post-war economic boom. This led to the development of our CL series with an enclosed mechanical clutch, which offers a compact size and low voltage design, ensuring precise and safe screw tightening.
Our AC VZ series of screwdrivers originated in the field of precision equipment assembly, but it remains the industry leader in Japan to this day.
Our newly developed BL series brushless screwdrivers (registered trademark) have recently begun to attract attention for their high durability. They are developed into environmentally friendly screw tightening electric screwdrivers that do not produce any harmful carbon particles.
We predict all next generation electric screwdrivers will follow this trend.
