The reported event that could be confirmed, since the product was returned for evaluation and matches the alleged failure mode.Device inspection revealed the following: the returned device shows signs of usage evident by intense scratches on the shaft of the screw.Appearance of heavy scratches on the screw surface and deformation of the head indicate that the insertion and/or extraction of the screw required great amount of force, possibly caused due to misalignment, consequently interacting with the nail and the washer.Some portion of the threads look flattened with faded anodization which is also indicative of the fact that the screw was not inserted properly and was rather misaligned.A review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.No indications of material, manufacturing or design related problems were found during the investigation.A review of the labeling did not indicate any abnormalities.Based on the above investigation, the root cause of the issue is user related as evident by the signs of misaligned insertion.If more information is provided, the case will be reassessed.
