In that period when the idea of quality control had not yet taken root in the manufacturing industry in Japan, Tohnichi focused on the importance of screw tightening control and developed the country’s first torque wrench. The control of torque is fundamental for quality control in various industries, particularly the automobile industry, and over the following 65 years Tohnichi has developed as the leading company for torque products.



Safety is essential to an affluent and convenient society based on advanced technologies. Our mission is to support social safety through quality improvement by adequate screw tightening control. Based on our developed torque technology and track record over the past 60 years, Tohnichi has been providing high-quality torque products and technical services to contribute to realization of an anxiety-free society as a comprehensive partner of torque technology which helps enhance reliability of your products and business.
