Rust prevention + friction coefficient management, improved torque management accuracy for screws.

One property that is closely related to surface treatment is the coefficient of friction (slip resistance). Particularly in screw products, variations in the coefficient of friction during fastening can lead to insufficient tightening or over-torquing, resulting in various issues such as loosening of screws or indentations in the mating material. Our surface treatment can enhance rust resistance while stabilizing within a specific range of friction coefficients, allowing for proper torque management. If you are experiencing difficulties with screw fastening, please consult us. Additionally, if you are currently applying lubricants separately, our surface treatment can control the coefficient of friction on its own, making it possible to eliminate the use of lubricants.
*Please note that the torque coefficient may vary depending on the conditions of the internal threads and the components being fastened.
