Research and Development System
Torque equipment used as work tools are subject to a severe working environment in daily operation. To lessen the load placed on workers as much as possible, Tohnichi products are developed through the use of sophisticated ergonomic studies.
Tohnichi innovations resulting from this approach are lightweight tools made of titanium and aluminum, which are ideal for the growing numbers of elderly or female workers on the production floor.
Further, our ergonomically designed tool handles and other parts are enjoying increased popularity throughout all sectors of our clientele. Also introducing 3D CAD system and 3D-printer, Tohnichi develops the ergonomics designed hand tools.

Durability Studies
While torque equipment requires high accuracy as a measurement device, it must also have sufficient ruggedness to ensure its performance as a work tool under severe conditions. In response, Tohnichi conducts research studies to help maintain the required levels of accuracy durability. (To learn more about torque tool accuracy and durability, click here.) Tohnichi endurance test room installs 10 machines, and operates the "type certification test" and "durability test" at the every new production development in order to assure accuracy and durability.

Torque Measurement Studies
Tohnichi is conducting research and development into higher accuracy testers that can precisely determine the accuracy of torque measurement devices. By studying the mechanisms of decreased reliability in these torque measurement, we are working to establish a traceability system.

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