Cleco 34RAA75AZ4 is a heavy-duty 34-Series pneumatic angle nutrunner built for demanding industrial fastening tasks. It uses a 1/2" square drive to handle larger sockets and fasteners. The tool offers a torque range of 28–55 ft-lbs, suitable for high-torque tightening jobs. With a free speed of 155 RPM, it emphasizes torque control and accuracy rather than high speed. Its indexable angle head and ergonomic design provide good access even in tight or awkward spaces. The nutrunner features oil-less blades (reducing oil mist in the work area) and a robust motor standard for the 34-Series. The built-in CLECOmatic clutch shut-off automatically stops the drive the moment the preset torque is reached — ensuring consistent, repeatable, and reliable fastening results.
