The Tohnichi TorqueWrench is not justanother Wrench

About 1.5 million final tightening operations, with zero human tightening errors!

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.
