All our production is generated from the most modern automated machinery (multispindle, CNC, transfer), where we work metal bars and forged material. All assembling (pre-mounted nut+ring, gaskets, o-ring, nuts) are performed in automated robotic stations.

New production has a special surface plating with a new ecological zinc/nickel passivation.

The grey colour product is film coated to guarantee:

• super protection against corrosion • optimal tightening torque
• correspondence with the European directives:
RoHS 2002/95/CE and ELV 2000/53/CE

We perform salt spray testing to confirm protection above 700 hrs.
