Through advance in torque technology, Tohnichi contributes to the creation of a safer world by helping to obtain the highest level of product safety in transportation, information technology, and many other fields that affect our daily lives.


The Tohnichi Torque Wrench is not just another Wrench


Our tightening assurance system eliminates various mistakes that occur during bolt tightening operations, and it even advises users how to perform tightening operations properly.


This is what one of our satisfied manufacturing customer claims two and a half years after beginning a Tohnichi’s tightening assurance system. The system has reduced human tightening errors in our factory to zero and has ensured proper control over all torque operations. Tohnichi’s products are a requirement to prevent a wide range of problems.
