The correct material of the component is steel Aisi 304 (asked telephonically to the supplier).

The AISI 304 is generally class A2 steel. Did you ask the state (annealed, hardened, etc)? Depending on the state one can define the resistance of the material. See https://github.com/icub-tech-iit/cad-mechanics/wiki/Technical-specification-standards#screws-bolts-and-nuts

Are you speaking about these 2 screws?

The Bossard code in wingst is BN2844... the material type indicated as "A2" only...

checking in the Wurth website I found the same screws with the material Type "A2-70" ; the same of the torx screws...

Do you think we can use the same?

@fiorisi @marcellosavoldi can we close this issue?

@fiorisi @marcellosavoldi can we close this issue?

Yes, let's use the A2-70.
