High Torque for bolting applications in structural steel
With a rated torque of 800Nm, the SIW 9-A22 can be used for structural bolting applications tightening bolts up to M24 in size. The gearbox housing and high-strength ¾” anvil make the tool robust enough for jobsite conditions.
Designed to increase accessibility and control
The slim diameter and integrated LED lights of the SIW 9-A22 make it easier to work in small spaces, while the handle and trigger have been developed to improve control for applications such as tightening pipe flange bolts.
New double hammer mechanism reduces vibrations
For setting larger diameter screw anchors such as the Hilti HUS3-H14 and Hilti HUS3-H10 we developed the double hammer mechanism that reduces vibrations, helping to increase safety in serial applications when working in concrete.
Features that help increase safety and productivity
Helping ensure operator and jobsite safety, the SIW 9-A22 uses an E-Spring that connects in a through-hole in the anvil to keep sockets in place, an additional retaining strap can be used to protect if the tool is accidentally dropped.

Hilti impact-ready sockets are designed for demanding applications
Hilti ¾” long impact sockets SI-S ¾” - L
¾” long sockets designed for impact wrenches are the universal solution, that gives you enough space within the sockets to drive it on your anchoring and bolting applications.
Hilti E-Springs
Only a through hole fixation ensures big sockets to stay on the anvil, not being a hazard for other workers on the jobsite. With the new Hilti E-Spring, through-hole socket fixation can be done in one step, ensuring no downsides in productivity.
HUS checking gauge
Lets you quickly check the wear of a HUS screw anchor and indicates whether the screw anchor can be reused. Can be fitted to the SIW 6AT-A22, SIW 22T-A and SIW 9-A-22 cordless impact wrenches
