ISO 10642, steel 08.8, zinc-nickel silver (ZNSHR)

Connection elements with a galvanised chromium (VI)-free zinc-nickel coating 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).



Overview of advantages:



  • Corrosion resistance of up to 720 hrs to base metal corrosion in accordance with DIN EN ISO 9227 NSS

  • Adjusted friction coefficient range of 0.12 μ–0.18 μ due to top coat with integrated lubricating particles, thermal capacity up to 120°C

  • Even coat distribution

  • Functional and decorative
Notice

DIN 7991 has been withdrawn and replaced by ISO 10642. There is some limited similarity (some head heights and head diameters changed | nominal Ø M18, M22, M24 removed | Stainless steels removed | strength classes 10.9 and 12.9 added).



Due to their head geometry, these screws can only be subjected to limited loads, see DIN EN ISO 898-1
