Manufacturer Narrative

The reported event could be confirmed.The investigation results showed that the screw broke as a result of too high torsional forces in forced rupture mode during the insertion.The fracture surface shows the typical flow structures of a ductile torsional breakage.The root cause of the failure was that after the screw contacted the plate, it was forcibly further turned.No indications were found for any material or manufacturing related issue.
