Connection elements with zinc-plated chromium(VI)-free thick-film passivation (ZSML) offer a future-proof alternative compared to surfaces containing chromium(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 for common zinc-plated 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 coating distribution
- Functional and decorative
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
