The series NERO.S comes from the need to produce a product that maintaining the efficiency and the quality of the ground screws can compete commercially with the rolled screws. The study and the engineering of parts, together with the application of specific production processes has allowed the SCARAVELLA F.lli select a particular range of measures, such as to satisfy a wide range of needs.
Screws series NERO.S are being provided with a maximum tolerance of 0.025mm and, on request, with zero backlash.
