(b)(6).The actual device was returned for evaluation.Reliability engineering evaluated the device and the reported condition was confirmed.A visual and functional assessment was performed on the device which found that the device did not hold a saw blade device.During service/repair, it was observed that the damaged set screw threads came off.The assignable root cause was determined to be due to normal wear out from use.If information is obtained that was not available, a follow-up medwatch will be filed as appropriate.
