Method: visual inspection; functional inspection; device history review; complaint history review; risk assessment; results: the returned connector was confirmed to have a jammed set screw.This was likely the result of the set screw being fully backed out past the acceptable position.However, the screw was torqued back to a usable position and was then found to be fully functional.No relevant manufacturing issues were identified during manufacturing record review.Conclusion: the most likely cause of the customer reported event is the customer fully backing out the set screw past its usable position, which resulted in its jamming.
