Episode.4: Supporting the Needs of the Era for Safety of Large-size Vehicle Wheels with the TW1000N

From around 2003, the torque control of large-sized vehicle wheel nuts became an issue of social concern in Japan, and sales of the Tohnichi DQLE1000N torque wrench for large-sized vehicle wheel nut tightening showed rapid growth. In 2007, the year that Tohnichi total sales of torque tools surpassed 6 million units, the company exhibited a torque multiplier wrench exclusively for large-sized vehicle wheel nut tightening as a reference product at the Tokyo Motor Show in response to the need for "One person to be able to carry out tightening easily, cheaply and precisely". Sales of this model started next year as TW1000N, after which the TW2 series was launched.
