Surface Treatment Recommendations

Zinc Plating (Zn)

Standard corrosion protection for indoor and mild outdoor environments.

Salt spray: 96–200 hours | RoHS compliant (trivalent chromium)

Zinc-Nickel Alloy (Zn-Ni)

High-performance coating for automotive, marine, and harsh environments.

Salt spray: 720–1500 hours | Recommended for grade 8.8+

Hot-Dip Galvanizing

Heavy-duty protection for structural and outdoor applications.

Salt spray: 500–1000 hours | Thread tolerance adjustment required

Note for high-strength fasteners (Grade 10.9, 12.9): Electroplating processes require hydrogen embrittlement relief baking (minimum 4 hours at 200°C within 4 hours of plating). Contact our engineering team for grade-specific plating recommendations.
