Cleco 50ESN65HD4 NeoTek Inline Corded Electric Nutrunner | 50 Series | 900 RPM | 10.3 - 48.6 (ft-lbs) Torque Range | 1/2" Square Drive

Built for production assembly work that needs a higher torque range without moving into large-frame tooling, the Cleco 50ESN65HD4 NeoTek Inline Corded Electric Nutrunner delivers 10.3 - 48.6 ft-lbs of controlled fastening torque with a 900 RPM rundown speed. It's 1/2" square drive supports compatible socket-based fastening, while the inline body keeps the tool aligned with the joint for straight-access assembly stations, bench fixtures, and controlled fastening operations.

As part of the NeoTek 50 Series, the 50ESN65HD4 is a transducer-controlled nutrunner, meaning torque is measured directly during the fastening cycle rather than estimated from motor current alone. That makes it a strong fit for safety-critical and quality-controlled joints where repeatability, operator feedback, and fastening data are important. Configurable LED light rings, audible alerts, handle vibration, onboard tool memory, and preventive maintenance alerts help operators confirm each rundown while supporting production traceability.

Applications:

• Automotive and transportation assembly for controlled tightening of larger brackets, frames, mounts, and subassemblies.
• Industrial equipment manufacturing where 1/2" square drive socket fastening is required within the 14 - 66 Nm torque range.
• Aerospace and rail production cells that require torque verification, operator feedback, and documented fastening results.
• Fixture-mounted or bench assembly work where an inline tool helps keep the socket aligned with the fastener.
• Quality-controlled manufacturing lines using smart fastening systems for batch counting, data logging, and process monitoring.

FAQs:

• Q: What type of work is the Cleco 50ESN65HD4 best suited for?
  A: This model is used for controlled production tightening on joints requiring 10.3 - 48.6 ft-lbs of torque. It is a good fit when the application needs more torque than smaller 3/8" drive NeoTek inline tools but still requires precision fastening feedback.
• Q: What does the 1/2" square drive mean?
  A: The square drive is the output that accepts sockets. A 1/2" square drive supports compatible 1/2" drive sockets for nut and bolt fastening within the tool’s rated torque range.
• Q: Is this nutrunner used like an impact wrench?
  A: No. This is a precision assembly nutrunner for controlled tightening, not a breakaway impact tool. It should be used for fastening applications that fall within the specified torque range and require controlled rundown, feedback, and traceability.
• Q: How does this model compare to the 50ESN43GD3?
  A: The 50ESN65HD4 offers a higher torque range of 10.3 - 48.6 ft-lbs and uses a 1/2" square drive, while the 50ESN43GD3 covers 6.6 - 31.7 ft-lbs with a 3/8" square drive. The 50ESN65HD4 is the better match when the joint requires higher torque and larger socket tooling.
• Q: Does this NeoTek tool require a controller?
  A: Yes. NeoTek corded electric nutrunners are part of a controlled fastening system and are typically used with a compatible Cleco controller. Confirm controller, cable, and software compatibility before ordering.
