Introducing the SIW 9-A22

Developed to meet the demands of the jobsite









SF 6H-A22 is fast and versatile

High Torque for bolting applications in structural steel

With a rated torque of up to 598 ft/lbs, the SIW 9-A22 can be used for structural bolting, tightening bolts upto M24. The gearbox housing and high-strength ¾” anvil make the tool durable enough for the toughest jobsite conditions.

Designed to increase accessibility and control

The slim diameter and integrated LED light on the SIW 9-A22 makes it easier to work in small spaces, while the handle and trigger have been developed to improve control for uses like tightening pipe flange bolts. 

SF 6H-A22 has power that's easy to handle

New double hammer mechanism reduces vibrations

For setting larger diameter screw anchors like the HUS3-H14 and HUS3-H10 anchors, we developed the double hammer mechanism that reduces vibrations, helping increase productivity 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, and a retaining strap can be used to help protect if the tool is accidentally dropped.
