Cordless impact wrench SIW 6AT-A22
& Adaptive torque module SI-AT-A22
With the introduction of the SIW 6AT-A22 and the SI AT-A22 module, Hilti
is expanding the SafeSet concept to mechanical anchors. The Adaptive
Torque (AT) system is designed to help you install the Kwik Bolt TZ and
Kwik Bolt 3 anchors more productively.
The SIW 6AT-A22, combined with the SI AT module, allows for faster
mechanical anchor installations than those installed with a cordless
impact wrench alone. This system helps avoid over and under torquing
anchors. Simply point the module’s barcode reader at the box of Hilti
anchors you’re installing, and pull the trigger. The module controls the
tool and provides immediate feedback, letting you know the anchor
is installed correctly and documents installation for easier quality
assurance. Get free tool calibrations with Hilti Fleet Management.
