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 hours against base metal corrosion in accordance with DIN EN ISO 9227 NSS
- Chromium(VI)-free
- Adjusted friction coefficient range from 0.09 μ-0.14 μ due to top coat with integrated lubricating particles
- Thermal capacity up to 120°C
- Even coating distribution
- Functional and decorative
ISO 10642 replaces DIN 7991 | There is some limited similarity (some head heights and head diameters have been changed | nominal Ø M18, M22, M24 are omitted | Stainless steels removed | strength classes 10.9 and 12.9 added).
These screws can only be subjected to limited loads due to their head geometry, see DIN EN ISO 898-1
