Fasteners – Non-Electrolytic Zinc Flake Coatings. ISO 10683:2018 specifies requirements and test methods for non-electrolytic zinc flake coatings on fasteners such as screws and bolts. These coatings offer corrosion protection without the need for traditional electrolytic processes. Zinc flake coatings provide excellent corrosion resistance even on complex geometries and are particularly important in automotive and construction applications. The standard covers specifications for coating thickness, adhesion, and corrosion resistance, as well as test methods to ensure compliance with these requirements.
