BOSCH Impact Wrenches (Electric)
Impact wrenches (electric) are tools used for tightening and removing nuts and bolts. Electrically powered impact wrenches deliver high torque to enable efficient tightening work. There are rechargeable and AC power supply types. They are used by attaching a socket to a rotating square drive, but the drive size varies according to the type of impact wrench. Be sure to choose a socket that matches the sizes of both the drive and bolts. The tightening torque is indicated for each model, so check this information and use the impact wrench for bolts that fall within the supported range. There are also types that can adjust the rotational speed and impact rate. Models with a larger drive size can tighten bigger bolts, and the size of the impact wrench itself normally increases with the drive size as well.
