Production Technologies

Cold Forming

We collaborate with plants equipped with multi-station machines, capable of producing large volumes in a short time, while maintaining competitive costs and high quality.

  • Customisable variants: head shape, impression type, threads (metric, self-tapping, plastic, self-forming, etc.).
  • Wide selection of materials with heat treatments (quenching and tempering, carburization) and galvanic coatings.
  • Guaranteed quality for all sectors and if required with selections up to a few PPM.
  • Components with captive ends or washers to optimize assembly and reduce assembly costs.

Hot forging

For larger diameters or smaller batches of special fasteners, we use hot forging.

– Heat treatments tailored to the required grade.

– Optimal finishes with pickling, passivation and specific coatings.

Forging for the Oil & Gas Industry

We manufacture large screws for drilling equipment and wellheads (Bonnet Bolt), guaranteeing the highest level of quality with:

– Advanced forging processes. – Mechanical tests on sacrificial parts and certified non-destructive testing

Precision Turning and Milling

For small customized batches, we perform turning and milling to design, creating:

  • Screws with grooves for o-rings.
  • Components with ground shank.
  • Almost artisanal productions for special needs.

Available Materials

  1. Carbon steel and alloy steels.
  2. Stainless steel (AISI 304, AISI 316, Duplex and Superduplex).
  3. Exotic alloys for extreme environments.
