When high torque and controlled rotation are required, the CS Unitec 6 1055 0075 Pneumatic Nutrunner delivers 0.9 HP, 40 RPM free speed, and 405 ft-lbs stall torque for low-speed, high-torque fastening, loosening, and valve-turning applications. Its 3/4″ male square drive accepts compatible industrial sockets, making it a strong fit for maintenance teams working on larger fasteners where control is more important than impact-style speed.This pneumatic nutrunner uses compressed air to provide steady torque output in production, plant maintenance, and field service environments. The 20 RPM load speed supports deliberate, controlled operation under resistance, while the angle-head configuration helps reach around machinery, piping, flanges, and other restricted work areas.Type: Pneumatic Nutrunner | Square Drive: 3/4″ Male | Power: 0.9 HP | Free Speed: 40 RPM | Load Speed: 20 RPM | Stall Torque @ 90 PSI: 405 ft-lbs | Drive Torque: 203 ft-lbs | Length: 25 in. | Air Consumption: 46 CFM @ 90 PSI | Air Connection: 3/8″ NPT | Hose I.D.: 1/2 in. | Side-to-Center Distance: 1-3/8 in.Features:High 405 ft-lbs stall torque supports low-speed, high-torque fastening and valve-turning work.40 RPM free speed provides controlled rotation for applications where fast run-down speed is not the priority.3/4″ male square drive accepts compatible industrial square-drive sockets.Angle-head configuration improves access around machinery, piping, flanges, and equipment frames.Reversible operation allows the tool to tighten and loosen fasteners without switching equipment.Pneumatic motor supports repeated use in facilities equipped with properly regulated compressed air systems.Applications:Valve operation where slow, controlled torque is required.Industrial maintenance teams servicing large fasteners on production machinery.Pipeline, flange, and mechanical equipment work requiring controlled pneumatic torque.Manufacturing and fabrication operations using 3/4″ square-drive industrial sockets.Plant MRO tasks where access around piping, frames, and equipment housings is limited.FAQs:Q: Why is this model slower than other CS Unitec nutrunners?A: This model trades speed for torque. Its 40 RPM free speed and 405 ft-lbs stall torque make it better suited for controlled high-torque work than fast nut run-down.Q: What does stall torque mean?A: Stall torque is the torque produced when the air motor stops under load. For this tool, the manufacturer lists 405 ft-lbs at 90 PSI.Q: What air supply does this nutrunner require?A: It requires 46 CFM at 90 PSI, a 3/8″ NPT air connection, and a 1/2″ inside-diameter air hose.Q: Can this replace an impact wrench?A: Not for every job. This nutrunner is better for controlled rotation and high-torque fastening, while impact wrenches are typically used for fast breakaway and impact-style loosening. .variation-details { width: 100%; max-width: 100%;
