An impact wrench is a cordless tool with a square drive that tightens and loosens bolts and nuts with high-torque rotary impacts.
What it is for
Used for vehicle maintenance, in the workshop and on the road and for tightening nuts and bolts where torque must be accurate and repeatable.
How to use it
Fit an impact socket of the exact nut size onto the square drive and secure it with the pin or ring. Select the mode and direction of rotation, seat the socket squarely and operate the tool while holding it firmly. For tightening to a specified torque, run the nut down with the impact wrench and finish with a torque wrench.
