The manufacturing of the products of the SOFAST Technologie range requires various technologies:
Shaping of the screw by deformation :
These different deformation stages go from the machine wire state to the hexagon head screw.
Heat treatment
In order to obtain a mechanical performance in compliance with the 8.8 or 10.9 quality classes, the SOFAST Technologie screws undergo quenching and tempering heat treatment
Surface treatment
For products requiring a high level of protection from corrosion, a zinc coating by hot-dip galvanising may be provided.
