• Rod: custom-made steel used in surface
processing, providing complete strength
towards traction.
• Nut: high safety steel (lead-free, systematic
control carried out after drawing
through Eddy currents and ultrasounds).
• Surface processing made through electrolytic
coating on the entire material (rod
& nut).

• 18/12 chrome-molybdenum steel with
very low carbon content, protected from
inter-granular corrosion.
• Fit in environments where 18.10 steels
stand up corrosion, excepted those involving
nitric acid.
• 2/2,5 molybdenum content allowing its
use in more applications than those complying
with 18.10 steels, particularly with
sulphuric acids and chlorides in marine
environments.
