Technical Standards & Compliance
Standard Compliance
- •ISO 19598 – Zinc-nickel electroplated coatings on fasteners. Specifies coating composition (10-15% Ni), thickness (8-15 μm), and corrosion performance requirements.
- •VDA 233-102 – Automotive corrosion testing standard. Zinc-nickel coatings are commonly referenced in VDA 233-102. Performance depends on coating thickness, composition, and test conditions.
- •ISO 4017 / DIN 933 – Full-thread hexagon head bolts. DIN and ISO standards are technically equivalent, ensuring international compatibility.
- •ISO 9227 / ASTM B117 – Salt spray testing standards. Performance depends on coating system and test conditions.
Coating System Specifications
- •Coating Type – Electroplated zinc-nickel alloy (Zn-Ni 12–15%)
- •Coating Thickness – 8-15 μm per ISO 19598
- •Passivation – Cr(III) trivalent chromium passivation (RoHS compliant)
- •Topcoat – Standard finish does not include topcoat. The zinc-nickel coating provides corrosion protection. Topcoat options available upon request for specific applications.
