ZCR351A-5 “Alligator” Yoke Riveters
“Alligator” Yoke Riveters
The ZCR351A-5 Alligator Yoke Riveters are precision pneumatic squeeze riveting tools designed for structural fastening tasks that need extended reach, precise rivet alignment, and controlled squeeze force. With an Alligator-style yoke setup, this riveter provides excellent access to edges, flanges, ribs, and recessed areas that traditional C-frame riveters struggle to reach. Built for reliable performance in demanding production and maintenance environments, the ZCR351A-5 delivers smooth pneumatic squeeze action with consistent force output. Its sturdy yoke design reduces flex during use, ensuring even rivet formation and consistent quality across high-volume assemblies.
