When controlled high-torque fastening needs to fit into tight spaces, the CS Unitec 6 1057 0099 Pneumatic Nutrunner delivers 73.5 ft-lbs of stall torque through a 1/2" male square drive for bolt installation and removal on machinery, assemblies, and maintenance work. Its 250 RPM free speed supports faster rundown before final torque, while the 125 RPM load speed reflects working speed under resistance. The 0.85 HP pneumatic motor and compact angle head help crews work where larger fastening tools may not have enough clearance.
