history

The history of Tohnichi’s 70+ years is the history of torque tools in Japan.

Tohnichi Manufacturing was established in 1949. 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 70+ years Tohnichi has developed as the leading company for torque products.
