RV2037-WR20

20V Brushless Closed Tube Nut Runner

  • Automotive and EV assembly lines — ideal for controlled fastening on studs and long threaded fasteners where enclosed access is required.

  • Industrial production and assembly — designed for high-precision tightening in repetitive, torque-critical operations.

  • Aerospace and transport manufacturing — suitable for applications requiring consistent torque accuracy and process control.

  • Appliance and white goods manufacturing — perfect for fastening deep-set or recessed fixings within housings and enclosures.

  • Machinery and equipment assembly — effective for installing shafts, studs, and threaded rods in confined or tubular structures.

  • Railway and commercial vehicle assembly — trusted for controlled tightening of safety-critical fasteners with limited external access.

  • Automation and semi-automated assembly lines — compatible with production environments requiring repeatability and reliability.

  • General industrial maintenance — ideal for servicing equipment where long fasteners or protected threads must be tightened accurately.

Tool Features

Technologies

Electronic Torque Control uses our advanced tightening technology to automatically shut off when the correct torque has been achieved. Different models will have alternative different stages to customize your workflow to optimize to the correct workload.

Our Electronic Pulse System is an electronic algorithm to dampen reactive forces for direct drive tools when they reach the desired torque. This process is achieved by pulsing the electric motor rather than applying continuous power to reduce the overall force applied to the user.

Our patent-pending All-In-One motor includes the power, control & communication board along with the automatic winding stator with an interior permanent magnet design rotor, all enclosed in a die-cast cover. These one-unit components have several advantages, including weight reduction, longer lifespan, and crucially our number one design goal of efficiency as there are no additional components to cool.

DC motors have traditionally been driven by carbon brushes to power the motor. Over time these wear out and need replacing. All our motors are brushless meaning that the motor is controlled electronically without the need for carbon brushes ensuring your tool is maintenance-free.

We have leveraged decades of electrical expertise from some of the world’s leading electrical engineers to develop our wireless platform to record and control our professional assembly tools, that can be remotely controlled via our software or different protocols for PLC systems.

Torque

Stages

Featuring different preset torque levels plus auto shut-off to offer precise control and consistent results across a variety of fastening tasks. Each stage corresponds to a different torque value (for example: 100 Nm, 200 Nm, 300 Nm, 400 Nm, 500 Nm, 600 Nm, 700 Nm), enabling the operator to select the exact torque requirement for the job and rely on the tool stopping cleanly when that limit is reached.

This multi-stage setting with auto shut-off means you can:

  • Avoid over-tightening critical fasteners and damaging threads or components.

  • Switch quickly between tasks requiring different torque levels without changing tools.

  • Ensure consistency across repeated assembly jobs, ideal for production or maintenance workflows.
