A fine hardened layer is formed on the surface of the screw! Prevents galling and seizure, which are disadvantages of titanium bolts.
We would like to introduce our manufacturing technology, "rolling processing." By applying high pressure with precision-ground rolling dies, a fine hardened layer is formed on the surface of the screws, preventing the drawbacks of titanium bolts, such as galling and seizure. Additionally, because rolled screws undergo plastic deformation that does not disrupt the material's structure, they do not compromise the inherent strength of the material. In contrast, cutting screws disrupt the material's structure, leading to reduced fracture toughness and increased crack propagation speed. The screw parts of our products correspond to JIS B 0205 (Grade 2), JIS B 0207 (Grade 2), JIS B 0206 (2A), and JIS B 0208 (2A). We can accommodate sizes from M3×0.5 to M42×4.5. 【Features】 ■ Formation of a fine hardened layer on the screw surface ■ Prevention of galling and seizure ■ Rolled screws undergo plastic deformation without disrupting the material's structure ■ Preservation of the material's inherent strength *For more details, please refer to the related links or feel free to contact us.

Company information
Recently, we continuously create special steels, always seeking the best ideas, unafraid of failure, and driven by traditional experience and an insatiable curiosity, finishing them as bolts. As a bolt manufacturer originating from Japan, we connect industries, companies, machinery, and people around the world. Utilizing our processing technology for difficult-to-cut titanium alloys, we have built a track record with a wide variety of steel materials, including nickel-based alloys and high-strength stainless steel. Our "rolling" and "hexagonal hole punching" processes have received high praise from many companies seeking "non-deforming bolts." Recently, we have also accumulated delivery records for semiconductor-related, high-pressure pump-related, and chemical plant applications. Products made from titanium alloy Ti-6Al-4V are produced by cutting and rolling "forged materials" and "round materials" to create the threaded parts, exceeding the strength of the material and ensuring optimal quality as bolts. Our products have contributed to the realization of Japan's cutting-edge industrial technology, bringing numerous victories in harsh racing scenes.
