Company information
Since our establishment, we have promoted manufacturing that is loved by professionals and provided "satisfaction," "emotion," and "value" through solving challenges related to "fastening." On November 1, 2013, we changed our company name from "Maeda Metal Industry Co., Ltd." to "TONE Co., Ltd." with a determination to leap and grow as a further global company. We have expanded our field from professional working tools to torque management equipment and bolt fastening equipment, and we are also developing a new field of bolting equipment that combines the strengths of these products. We will continue to be committed to "fastening," which is deeply engraved in our company's DNA, aiming to be the brand chosen by our customers—TONE. Please look forward to TONE's evolution as we build the foundation for the future with bolting solutions.
