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

  • Chrome(VI)-free

  • Adjusted friction coefficient range from 0.09μ - 0.14μ due to top coat with integrated lubricating particles

  • Thermal capacity up to 120°C

  • Even coating distribution

  • Functional and decorative
Notice

ISO EN 1661 replaces DIN 6923 | There is some similarity | Fine thread removed | Width across flats for size M10 changed from 15 mm to 16 mm.
