Well, we need to calculate force/load from screw size: load = cross section x stress. These are the cross-sectional areas of different screws and the resulting forces at 1100MPa: M5: 14.2mm² 15.62kN M6: 20.1mm² 22.11kN M7: 28.9mm² 31.79kN M8: 36.6mm² 40.26kN M10: 58.0mm² 63.8kN M12: 84.3mm² 92.73kN In the video a M10 screw was tested, so the load was in approx. 64kN. I hope that answers your question.
1100 MPa !
so if we consider that screw of M8 size
it's about 220 kN maximal Force ??
