Connection elements with a galvanised chrome (VI)-free zinc-nickel coating (ZSML) offer a more future-proof alternative compared to surfaces containing chrome(VI). The coating consists of a zinc layer with passivation on a (chrome III) basis and sealing coat (top coat with integrated lubricating particles).
Overview of advantages:
- Higher quality replacement of common galvanised coatings such as A2C or A3C
- Adjusted friction coefficient range from 0.09 μ - 0.14 μ due to top coat with integrated lubricating particles
- Thermal capacity up to 120°C
- Even layer distribution
- Functional and decorative
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.
