Company information
Established in 1917, during the dawn of mass production of screws in Japan, the company succeeded in producing the first domestic cross-recessed screws in 1949 and cooperated with the government to localize tapping screws in 1954. The company holds data on over 200,000 types of screws and bolts, enabling the high-quality manufacturing of various shaped products. Recently, it has focused on investing in research and development, working on tapping bolts with a diameter of 6mm or more, high-strength aluminum bolts, tapping screws for thin steel plates, and tapping screws for CFRP, which will support the next generation. The company is committed to innovative technological development without being bogged down by history.
