ZCR351AT-5 “Alligator” Yoke Riveters
“Alligator” Yoke Riveters
The ZCR351AT-5 Alligator Yoke Riveters are precision pneumatic squeeze riveting tools designed for structural fastening applications requiring extended reach, accurate alignment, and controlled rivet-forming force. Featuring an Alligator-style yoke configuration, this riveter enables effective access around edges, flanges, and recessed structural areas where conventional riveting tools have limited clearance. Engineered for reliability and repeatability, the ZCR351AT-5 delivers smooth pneumatic squeeze action with stable force output. Its rigid yoke construction minimizes flex during operation, ensuring uniform rivet formation and consistent installation quality across repetitive production or maintenance tasks.
