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.Type: Pneumatic Nutrunner | Model: 6 1057 0099 | Drive Size: 1/2″ M Square Drive | Stall Torque: 73.5 ft-lbs | Free Speed: 250 RPM | Load Speed: 125 RPM | Power: 0.85 HP | Oil Flow: 46 GPM | Side-to-Center Distance: 1″ | Length: 21″ | Weight: 11 lbs | Air Connection: 3/8″ NPT | Hose Size: 1/2″Features:Worm gear drive provides high torque output for controlled nut and bolt fastening.Compact angle head improves access around frames, housings, machinery guards, and other obstructions.Reversible operation supports both fastening and loosening tasks with the same tool.1/2″ male square drive connects directly with compatible impact-rated sockets and drive accessories.250 RPM free speed helps reduce rundown time on repetitive assembly and maintenance jobs.11 lb tool weight gives the nutrunner a manageable balance for field service and plant use.Applications:Industrial maintenance and MRO fastening on machinery, brackets, covers, and bolted assemblies.Equipment repair work where an angle-head nutrunner helps reach bolts in recessed or obstructed areas.Fabrication and assembly stations requiring controlled pneumatic rundown on medium-torque fasteners.Fleet, plant, and shop service tasks where repeatable nut and bolt installation is preferred over manual wrenching.FAQs:Q: What does stall torque mean on this nutrunner?A: Stall torque is the torque produced when the tool stops under load.
