Decorative black finish
Fasteners with a zinc-plated chromium (VI)-free zinc-nickel black coating (ZNBHL) 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 – 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
 - 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
 
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
