URYU U-900 Pneumatic Nutrunner

The URYU U-900 Pneumatic Nutrunner is a 1/2" square-drive, pistol-grip fastening tool designed for controlled pneumatic bolting in medium-duty applications. Powered by compressed air at 72–85 psi (0.5–0.6 MPa) with a 1/4" NPT inlet, it delivers forward and reverse torque for consistent tightening in automotive assembly lines, machinery fabrication, and general production environments. Weighing approximately 1.36 kg (3.0 lb), this nutrunner is part of URYU's pneumatic fastening system and is used for replacement and industrial assembly service, supporting repetitive fastening tasks and process optimization. Manufactured in Japan, the U-900 is commonly paired with or complemented by URYU U-100EC Air Impulse Torque Wrench and URYU UX-900S Pulse Tool as common replacements.
