    ADDITIONAL INFORMATION: D9, G3, H3, H6. THE COMPLAINT ALLEGATION WAS CONFIRMED. ONE UNPACKAGED AR-8827L-14 BATCH UNK WAS RECEIVED FOR EVALUATION. VISUAL INSPECTION REVEALED DAMAGE TO BOTH THE HEAD HEXALOBE AND THE BODY THREADS. THE OBSERVED DAMAGE APPEARS CONSISTENT WITH MECHANICAL STRESS, LIKELY INCURRED DURING USE OR HANDLING. A FUNCTIONAL TEST WAS PERFORMED USING A WELL-KNOWN GOOD PLATE (AR-2656DL), AND IT WAS OBSERVED THAT THE SCREW SITS PROPERLY IN THE PLATE'S HOLE. THE DEVICE WAS EVALUATED ACCORDING TO THE DRAWING SPECIFICATION. C1330 AT REVISION 11, COMPONENT C1330-03 AT REVISION 9. OVERALL LENGTH: 0.551 ± 0.012 INCHES. RESULTS: 0.555 INCHES.
