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.

In comparison to existing black surface treatments, our painting-based surface treatment proposal can improve appearance quality and corrosion resistance. In the standard specification, a silver-based coating is applied with a black topcoat, but if you want to further stabilize the black color, we can also offer options such as using a black base coat. Please feel free to consult us when looking for black surface treatments.

By changing the material of stainless steel products to iron and applying our company's high corrosion-resistant surface treatment, it is possible to achieve a total cost reduction. We will listen to your requirements for rust prevention performance and specifications, and propose the most suitable surface treatment. We can accommodate small sample production, so please feel free to consult with us.
