Manufacturer Narrative

This follow-up report is being submitted to relay additional information.The complaint is confirmed.The 1.5x4mm ht sd x-dr scr 5-pk (part# 95-6104, lot# unk) were returned for investigation.The screws were visually evaluated and found to show signs of use.The screws showed significant damage at the cross-drive interface on the head of the screw.Functional testing was done for retention using a driver 01-7390 lot 048760 and bit 15-1196 lot 406650.The blade was inserted into the driver and the screws, the assembly was then lifted by the screw to verify the cross-drive feature could support the weight of the blade and driver.The screws failed this retention test.The dhr will not be reviewed as the lot number remains unknown.There are no indications of manufacturing defects.For this part (95-6104) and the previous one year (from the notification date) regarding retention failure, there is a complaint rate of 0.05% which is no greater than the occurrence listed in the application fmea.The most likely underlying cause of the complaint is excessive force beyond what the screw is designed to encounter on the screw head during use.Potential contributing factors are using a worn or incorrect blade and incorrect alignment of the blade and screw.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.The following fields were updated: b4 date of this report b5 describe event or problem d10 device availability g4 date received by manufacturer g7 type of report h2 follow up type h3 device evaluated by manufacturer h6 method code h6 results code h6 conclusions code h10 additional narratives/data.
