Those dings and chips are from the phosphate operation, throwing the parts into a box, not taking the time to place them proper and protect the threads. They are supposed to provide webbing to put over the parts. The Chinese system failed. The threads are single pointed. Not enough volume to roll the threads or set up equipment for rolling threads, and die cut threads are not acceptable for this part. As for implementing a CAR (correction action report) to fix the process, well, lets just say, reject the parts and these people will think the Communist leader will pay them a visit with whip. The fear of this will make them fix anything to make it right!!!! As for all this costing more per part, it doesn't, like it does here. They say the Chinese government subsidises these things to keep cost down.I'm guessing he already knows the cause of the defect so his job is to validate what he already knows. The rolls are worn and chipped or loose chips are in the rolling machine.
