ZCR351A-918 “Alligator” Yoke Riveters
“Alligator” Yoke Riveters
The ZCR351A-918 Alligator Yoke Riveters are precision pneumatic squeeze riveting tools designed for structural fastening applications requiring extended reach, controlled squeezing force, and accurate rivet alignment. Featuring an Alligator-style yoke configuration, this riveter provides enhanced accessibility around structural edges, flanges, and recessed assembly areas where traditional C-frame riveters may not provide sufficient clearance. Engineered for consistent performance in demanding production and maintenance environments, the ZCR351A-918 delivers smooth pneumatic squeeze action and stable force output. Its reinforced yoke structure minimizes deflection during operation, ensuring uniform rivet formation and repeatable installation quality in both high-volume and precision assembly work.
