Fasteners with a galvanised chromium(VI)-free zinc-nickel-plated silver coating (ZNSHL) are suitable for applications with a high risk of corrosion. The coating comprises a zinc-nickel alloy layer and a sealing coat (top coat with integrated lubricating particles).
Corrosion resistance:
- Diameter ≥ M2 - 360 h*
- Diameter ≥ M4 - 600 h*
- Diameter ≥ M10 - 720 h*
- *No base metal corrosion in areas without thread in salt spray tests according to DIN EN ISO 9227 NSS
Overview of advantages:
- Resistance of up to 720 hours against base metal corrosion in accordance with DIN EN ISO 9227 NSS
- Chromium(VI)-free
- Adjusted friction coefficient range from 0.09-0.14 μ due to top coat with integrated lubricating particles
- Thermal capacity up to 120°C
- Even coating distribution
- Functional and decorative
