Choosing the right torque wrench

For improved speed and consistency with ETA or ICC-ESR approval, choose the Adaptive Torque System

When your priority is speed, and you can't compromise on safety, choose the SIW 6AT-A22 Impact Wrench and SI-AT-A22 Adaptive Torque System.

Putting you in control, the AT System is ideal for installing Hilti expansion anchors, performing metal-to-metal bolting or installing modular support systems so you can undertake the most demanding applications, without compromising on performance.

Hilti Adaptive Torque System
these machines are ideal and work faster than a manual torque wrench

Construction and engineering professionals know the advantages and disadvantages of 'torqueing'. It's a proven installation method, yet requires a calibrated torque wrench to ensure correct installation of expansion anchors, modular support systems or metal bolts without causing damage to base materials or a risk to safety.

Our Adaptive Torque System helps to remove these problems.
Sensors and on-board intelligence in the SIW 6AT-A22 and SI-AT-A22 help to ensure the correct installation of your fasteners. It is in line with international regulations such as ICC-ESR or ETA approvals for Hilti expansion anchors. With the AT System you can work fast and save your manual torque wrench for final approvals.

What is the AT System?

Offering more power, precision and traceability, the Adaptive Torque System (AT System) is the perfect solution for anchoring, modular framing and bolting applications where you need to be better assured of correct pre-tensioning every time. The AT System is made up of five components:

  • SIW 6AT-A22 cordless impact wrench with intelligent electronics, a robust anvil and a sleek frontal portion which can reach into tight spaces
  • SI-AT-A22 module fits between the impact wrench and battery to process live data and displays when a fastener was correctly pre-tensioned
  • B22 batteries provide power to the impact wrench and SI-AT module with the ideal combination of high power and low-weight being delivered by our B22 batteries
  • Documentation software so that the SI-AT-A22’s job history can be transferred to a PC and used to create a detailed installation certificate
  • AT System-compatible products include consumables like Hilti wedge anchors or Hilti modular system connectors
