ZCR351AT-7 “Alligator” Yoke Riveters
“Alligator” Yoke Riveters
The ZCR351AT-7 Alligator Yoke Riveter is a precision pneumatic squeeze riveter designed for structural riveting applications requiring extended reach and precise force control. Featuring an Alligator-style yoke configuration, this riveter provides enhanced access to edges, flanges, and recessed structures that conventional C-yoke riveters cannot readily reach. Engineered for consistent performance in demanding industrial and aerospace environments, the ZCR351AT-7 delivers smooth pneumatic squeeze action with stable force output. Its rigid yoke structure minimizes deflection during operation, ensuring precise rivet alignment and uniform rivet formation across repetitive assembly tasks.
