MATERIALS:
Rivet nut: Steel C4C (EN 1.0303) / C10C (EN 1.0214)
SURFACE TREATMENTS:
Zinc plating: white zinc plated with Chrome III with minimum thickness of 7mm (Fe/Zn 7 IV). There is the possibility to add a protective sealant coating to increase the corrosion resistance (Fe/Zn 7 IV S).
The tensile test and the maximum clamping force test is carried out with steel screws of resistance class 12.9
