The flat square neck fixes the round head screw e.g. in a slot and allows tightening from the nut side without counter-tensioning.
Connection elements with zinc-plated chromium(VI)-free zinc thick-film passivation (VZD) offer a future-proof alternative to surfaces containing chromium(VI). The coating consists of a zinc layer with passivation on a chromium (III) basis.
Overview of advantages:
- Chrome(VI)-free alternative to A2C or A3C
- Thermal capacity up to 120°C
- Even coating distribution
