We offer a wide range of sizes! Introducing thick hexagon socket bolts with strength classification 12.9.
We recommend the "Large Diameter Hexagon Socket Bolt Strength Class 12.9" for molds and industrial machinery. Traditionally, for domestically produced large diameter hexagon socket bolts exceeding M20, those of strength class 10.9 were available in the market. Therefore, when bolts of strength class 12.9 were absolutely necessary, we had to resort to custom manufacturing, which increased costs. However, thanks to the Taiwanese screw manufacturer YFS, we can now maintain a constant stock of hexagon socket bolts of strength class 12.9 with nominal diameters M22, M24, and M30 in Japan, greatly improving availability. We encourage you to consider this option. 【Product Lineup】 ■M22 ■M24 ■M30 *For more details, please refer to the PDF document or feel free to contact us.
