Norbar Torque Tools manufacture an extensive range of high quality torque wrenches to cover torque values from 1 N·m to 2000 N·m. They are designed and manufactured to exceed international standards for accuracy.

In addition to the normal ‘adjustable’ torque wrenches, Norbar offer Production ‘P’ Type versions which can be pre-set and dedicated to a particular application. This setting system is designed to discourage unauthorised alteration.

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.
