We offer a wide range of sizes! Introducing thick hexagon socket bolts with a strength classification of 12.9.
We recommend the "Large Diameter Hexagon Socket Bolt Strength Class 12.9" for molds and industrial machinery. Traditionally, for domestic products, hexagon socket bolts with a diameter exceeding M20 were available only in strength class 10.9. Therefore, when a strength class 12.9 bolt was absolutely necessary, it had to be custom-made, resulting in increased costs. However, thanks to the products from YFS, a Taiwanese screw manufacturer, we can now maintain a constant stock of strength class 12.9 hexagon socket bolts with nominal diameters of 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.
