Fasteners with a zinc-plated chromium (VI)-free zinc-nickel 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 — 360h*

  • Diameter ≥ M4 — 600h*

  • 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 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
Notice

ISO EN 1665 replaces DIN 6921 | There is some limited similarity | Some head heights changed | Flange diameter is unchanged | Widths across flats for M10, M12, M14 and M16, M20 changed | Strength 12.9 removed | Fine thread removed.
