HIGH-STRENGTH FASTENERS FOR AUTOMATIC ASSEMBLY CAN ONLY BE DESIGNED AND MANUFACTURED BY INCORPORATING FUNDAMENTAL ENGINEERING AND QUALITY CONCEPTS. STARTING AT THE EARLY DESIGN STAGE, A SPECIAL BOLT DESIGN SHOULD BE DEVELOPED BY CLOSE COOPERATION BETWEEN USER AND MANUFACTURER. BEFORE AND DURING PRODUCTION THE APPROPRIATE QUALITY CONTROL MEASURES ASSURE A HIGH LEVEL OF DEFECT-FREE PRODUCTION. ALL OF THESE MEASURES CANNOT COMPLETELY PREVENT ACCIDENTAL FAULTS. TO AVOID THESE FAULTS, IT IS NECESSARY TO AUTOMATICALLY 100% INSPECT AS A LAST PRODUCTION OPERATION IN CONJUNCTION WITH AUTOMATIC PACKING. ONLY WITH THIS TOTAL CONCEPT, COMBINING ALL APPROPRIATE PRINCIPLES, IS INTERRUPTION-FREE FEEDING AND ASSEMBLY OF FASTENERS POSSIBLE.
