The Nero. S series comes from the need to create a product that, while maintaining the efficiency and quality of ground screws, can compete commercially with rolled screws. The study and the engineering of parts, together with the application of specific production processes has allowed SCARAVELLA F.lli to select a particular range of sizes to satisfy a wide range of needs.

The Nero.S series screws are provided with a maximum tolerance of 0.025mm and, on request, with zero tolerance.
