[Introduction to Manufacturing Technology] Rolling Process

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.
