By entering straight into the boss, we stabilize the quality of the joint. With a thread shape created by natural science, it is also excellent in reusability and can be used multiple times.
■Excellent fastening performance The newly developed screw section provides high pull-out strength, high break torque, and high axial force. The tip is designed to enter the pilot hole straight, making it suitable for automation using robots. The counterbore can be shortened to about one-third of existing products, allowing for a reduction in boss depth. Due to low friction during screwing, it can be screwed in at high speeds, minimizing heat generation and preventing damage to the resin. It is also suitable for hard resins like GF-40 and has good reusability. ■EVO PT is a new technology developed by the German company EJOT. EJOT products have a proven track record as high-performance fasteners primarily for the automotive industry. ■Yamashina, as the official Japanese licensee of EJOT, designs, manufactures, and sells over 100 million EJOT products annually, supplying more than 60% to the automotive sector.

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.
