Fasteners with a zinc-plated chromium (VI)-free zinc-nickel black coating (ZNBHL) 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 – 360h*
 - Diameter ≥ M4 – 480h*
 - Diameter ≥ M10 – 720h*
 
- *No base metal corrosion at points without thread in salt spray mist testing according to DIN EN ISO 9227 NSS
 
Overview of advantages:
- Corrosion resistance of up to 720 hrs to base metal corrosion in accordance with DIN EN ISO 9227 NSS
 - Chromium(VI)-free
 - Adjusted friction coefficient range of 0.09 μ–0.14 μ due to top coat with integrated lubricating particles
 - Thermal capacity up to 120°C
 - Even coat distribution
 - Functional and decorative
