 Research and Development |
 Torque equipment used in the field is subject to the rigorous demands of daily operation. Therefore, to ensure greater utility and reliability, Tohnichi products are developed through the use of sophisticated ergonomic studies. Among the many Tohnichi innovations resulting from this approach are lightweight tools made of titanium and aluminum. These are ideal for the growing numbers of elderly or female workers on the production floor. In fact, our ergonomic tools are enjoying increased popularity throughout all sectors of our clientele. |

| Studies on Screw-Tightening Reliability |
 Tohnichi regularly conducts studies to enhance the reliability of bolt tightening. Notably, our studies on error-proofing techniques to prevent bolts from being left untightened have resulted in the development of FM-type wrenches and marking torque wrenches. These tools help operators to ensure that all bolts are tightened to the appropriate degree. Tohnichi has even developed a variety of checking devices designed to improve the reliability of tightening equipment. Moreover, we provide devices and computer software for more timely, accurate management of tightening data. |

| Durability Studies |
 While torque equipment requires high accuracy in the aspects of measurement, it must also have sufficient ruggedness to ensure its performance in extended use. In response, Tohnichi research studies help maintain the required levels of accuracy and durability. In fact, the quality of our products is guaranteed via accuracy and durability testing of 100,000 and 1 million cycles, respectively. |

| Torque-Measurement Studies |
| Tohnichi is a front-runner in the research and development of testers that can precisely determine the accuracy of torque-measurement devices. By studying the mechanisms of decreased reliability in torque measurement, we have established an effective testing system for torque equipment, along with a traceability system that sets a national standard. |
