Connection elements with a galvanised chrome (VI)-free zinc-nickel coating (ZNBHL black or ZNSHL silver) are suitable for applications with a high risk of corrosion. The coating comprises a zinc-nickel alloy layer and a seal (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 from 0.09μ - 0.14μ due to top coat with integrated lubricating particles
  • thermal capacity up to up to 120°C

  • Even coat distribution

  • Functional and decorative

Notice

Hardness class 45H corresponds to a hardness of 450 HV



The standard tip has an angle of 90°, but very short lengths have an angle of 120°.



Steel set screws are intended for use under compressive stress only (see also DIN EN ISO 898-5). Typical uses include clamping in an adjusting ring or applying pressure to a counterpart. Steel set screws are therefore extremely hard in order to ensure torsional strength in the hexagon socket during tightening/loosening.



Tip:


A2/A4 stainless steel set screws are not specially hardened and may be used for tensile loads.



ISO 4027 replaces DIN 914 | There is some similarity | Nominal diameters for M1.4, M1.8, M14, M18, M22 are removed | Hardness classes for stainless steels introduced.
