nuts. An incorrect size impact socket will result in inac-
curate and inconsistent fastening torque and/or damage
to the bolt or nut.
Align the square of the impact socket with the square
drive and push the impact socket onto the square drive
until it locks into place. Tap it lightly if required.
To remove the impact socket, simply pull it off.
