Many successful applications in Shinkansen! Higher strength than cutting processing, and capable of mass production as well as custom orders! We also offer prototyping, so please feel free to consult with us.
♦P.C. Tie Rod Trapezoidal Screw Bolt♦ The "trapezoidal screw/bolt" for concrete ties is manufactured using the "hot-rolled rolling method," which offers superior strength compared to machining. It has already been successfully used in numerous cases for the Shinkansen and can also be used for securing parts such as the hanging sections of concrete walls in civil engineering and underground areas. ★Please feel free to consult us regarding other applications or prototypes. We also design "male threads." 【Features of the Hot-Rolled Rolling Method】 - Maintains the fiber structure of the steel, providing excellent strength - High precision with no eccentricity - Suitable for mass production - Custom products for special shapes/trapezoidal screws are also available ♦Connection Plate Bolt and Nut♦ Standard steel connection plate bolts and heat-treated connection plate bolts. 【Features】 - Heat-treated connection plate bolts are produced in three grades: 5.6, 8.8, and 10.9 - Obtained JIS display permission (certification) ◆Prototype Forged Parts◆ If you provide us with drawings, we can design and prototype molds regardless of quantity! This allows for pre-processing by forging, not only for bolts but also for complex shapes or when you want to reduce excess material in lathe machining. *For more details, please contact us or refer to the catalog.*
