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 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

Notice

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
