CS Unitec 6 1056 0075 Pneumatic Nutrunner | 0.9 HP | 120 RPM | 133 (ft-lbs) Stall Torque | 3/4' M Square Drive

When controlled torque matters more than impact force, the CS Unitec 6 1056 0075 Pneumatic Nutrunner provides 0.9 HP, 120 RPM free speed, and 133 ft-lbs stall torque for tightening, loosening, and valve-turning work in industrial maintenance and assembly environments. Its 3/4" male square drive accepts compatible industrial sockets, while the worm gear drive helps deliver steady torque output for applications where fastener control is critical.

This air-powered nutrunner is built for shops and plants with compressed air systems already in place. The 67 RPM load speed supports controlled operation under working load, and the compact angle head helps the tool reach around piping, machinery, flanges, and other confined work areas where straight tools may not fit.

Type: Pneumatic Nutrunner | Square Drive: 3/4" Male | Stall Torque @ 90 PSI: 133 ft-lbs | Drive Torque: 68.3 ft-lbs | Free Speed: 120 RPM | Load Speed: 67 RPM | Length: 21 in. | Power: 0.9 HP | Hose I.D.: 1/2 in. | Air Connection: 3/8" NPT | Air Consumption: 46 CFM @ 90 PSI | Side-to-Center Distance: 1 in.

Features:

• Worm gear drive provides controlled torque transfer for nut running and valve-turning applications.
• 3/4" male square drive fits compatible industrial sockets.
• 133 ft-lbs stall torque supports higher-torque fastening than faster, lower-torque models in the same family.
• Compact angle head improves access around piping, equipment frames, and tight work areas.
• Reversible operation supports both tightening and loosening tasks.
• Pneumatic motor is suitable for facilities using compressed air as a primary power source.

Applications:

• Plant maintenance teams tightening and loosening nuts on production equipment.
• Valve operation where controlled torque and angle-head access are required.
• Fabrication and assembly work involving 3/4" square-drive sockets.
• Pipeline, flange, and machinery service in compressed-air work environments.
• Industrial MRO tasks requiring repeatable pneumatic torque output.

FAQs:

• Q: What does stall torque mean on this nutrunner?
  A: Stall torque is the torque level reached when the air motor stops under load. For this model, the manufacturer lists 133 ft-lbs at 90 PSI.
• Q: What air supply is required?
  A: This model requires 46 CFM at 90 PSI, a 3/8" NPT air connection, and a 1/2" inside-diameter air hose.
• Q: Is this the same as an impact wrench?
  A: No. A pneumatic nutrunner applies controlled rotational torque, while an impact wrench uses repeated hammering blows for breakaway force.
• Q: What sockets work with this model?
  A: This model uses a 3/4" male square drive and should be used with compatible 3/4" square-drive industrial sockets.
