Impact wrenches

Wrench

— a device for tightening and loosening nuts and other similar parts — for example, bolts with heads without slots. In many ways, they are similar to screwdrivers — to the extent that some models can be used in this capacity by installing a cartridge under the bit. However, the standard version of nozzles for wrenches are sockets mounted on a “square” mount of one size or another (see “Chuck”).
