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 domesticate tapping screws in 1954. We hold data on over 200,000 types of screws and bolts, enabling us to manufacture a variety of products with high quality. Recently, we have been focusing on research and development investments, 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. We are committed to challenging innovative technology development without being bound by history.
