Advanced performance and functionality

Advanced performance and functionality

To make eTensil an advanced tightening system, it has smart units that work in perfect synergy with the tools to enable various functions and extend the programming and customisation options for which the tools were designed.

The numerous models available in the two ranges of solutions provide power at the right voltage, continuous monitoring of the tool status and work cycle or control and programming throughout the tightening process.

They are entirely designed and built by Fiam, and are a strategic choice to offer one of the most advanced industrial production solutions in terms of efficiency and operational versatility.

“Smart Pro”  advanced programming

for solutions with torque control and automatic power supply shut-off.

eTensil is the only electric screwdriver on the market with automatic power supply shut-off that can change tightening mode without changing the mechanical configuration. It offers four pre-set tightening modes.

Another six functions are available through the reverse button and lever:

1 starting block in case of an anomaly

2 front  illumination LED

3 Untightening

4 Soft Start: slow screwdriver start (from stopped to rated speed in approx. 1.5 seconds)

5 Pre-auto untightening by 4 turns (1400 degrees): A useful feature when you have previously tightened parts that need loosening before being tightened to the set torque;

6 Post-auto untightening by 4 turns (1400 degrees): A useful feature when needing to tighten to the set torque and then loosen for a subsequent assembly.

TPU M1 monitoring unit represents a great innovation able to monitoring and managing all tools functionalities.

Here are some functions: essentials to monitoring a tightening process correctly and making it reliable.

  • It automatically recognizes the tool connected and configures themselves immediately to its parameters, so operators cannot make initial setup errors
  • Displays the tightening outcome OK/NOK in addition to the tightening time
  • Screws counting: this function turns the system into an effective Poka Yoke device
  • It detects process anomalies, for example stripped threads or screws already tightened
  • Store up to 99 tightening operations
  • It communicates with the outside, the PLC or other devices, and can be controlled remotely
  • It solves tightening situations with critical joints, for example with flexible gaskets, or components made of rubber or other materials.

“Smart Pro Evo” advanced programming

for torque/angle control solutions based on current absorption.

In these solutions, the power supply and control units are the «smart core” that programs, monitors and controls all functions of the tools associated with it.

These sophisticated instruments not only provide tools with the correct power supply, but also feature a large number of programmable functions compared to others on the market, and are faster, simpler and more intuitive to use.


Other functions can be activated/deactivated acting directly on the control unit:

  • CLOCKWISE or counterclockwise tightening.

The main feature of these advanced units is the possibility to set different control functions:

  • SOFT START. The ramp speed acceleration is not fixed but it is possible to set the time acceleration to ease screw engagement
  • TOOL SPEED can be set within the minimum / maximum range
  • FRONT LED LIGHTING adjustable with intensity from 0 to 100%
  • PRE-SELF UNTIGHTENING:it is possible to set the untightening angle and the pause between the untightening and the subsequent tightening. This strategy finds its application in the electrical/electronic field, for example when it is necessary to open and then close connectors to insert electrical wires.
  • POST-SELF UNTIGHTENING:it is possible to set the untightening angle as the pause time between untightening and subsequent tightening.
  • STOP-BY-TIME TIGHTENING: When it is necessary to tighten threaded fasteners to a certain height and not to a defined torque. This is made by checking the tightening time.
