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 0.09μ - 0.14μ due to top coat with integrated lubricating particles

  • Thermal capacity up to 120°C

  • Even coating distribution

  • Functional and decorative
Notice

Increase in assembly productivity



When elements are joined using hexalobular (TX) fasteners, the force is transmitted over a large surface area across the flanks of the drive rather than being centred on one point, as is the case with hexagon socket drives, for example. This has a number of advantages:


  • Reduced tool wear

  • Tool does not slip because force is distributed optimally

  • No damage to surface coating

  • No wobbling

  • Screw locates securely


Hexalobular drives must comply with DIN EN ISO 10664


  • As a result, connection elements with hexalobular heads are standardised and can be used all over the world
