basic information
■ With a small lead angle of 7-8° and a small pitch in a perfectly circular shape, it is resistant to loosening and maintains high pull-out strength. At the same time, it achieves fastening with high axial force. ■ The resin has a screw thread shape that allows it to flow smoothly into the screw valley, forming a solid female thread. Additionally, this screw thread shape enhances repeatability and prevents damage to the boss. ■ Manufactured with boron steel that has been heat-treated and tempered. The strength classification is 10.9, ensuring mechanical strength. *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/.*

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.
