Zinc-Nickel Coating (ZnNi) in Fasteners – When Is It Worth Using?
Why Standard Zinc Coating Is Often Not Enough In many industrial applications – especially in hydraulics, agriculture and automotive – fasteners are exposed to conditions that quickly reveal the limits of standard corrosion protection. Moisture, salt, temperature changes and mechanical stress can significantly reduce the lifespan of typical zinc-plated components. The result is predictable: corrosion, difficult disassembly, reduced joint reliability and higher maintenance
