First of all, it is necessary to understand why impact wrenches are so important. It is a tool that is used for fastening activities. In other words, it is used to unfasten and fasten lug nuts, bolts, fasteners, etc. A perfect example of usage of such tools may be a tire changing. To change a tire you need to unfasten lug nuts.

These nuts are fastened tight enough to make sure they will no unfasten during movement. Having unfastened the lug nuts you can take off the wheel and put a new one. After that, you need to fasten lug nuts. You can do it manually and it is not a big deal if you need to change only one tire, but what if you need to change all four tires? It may be challenging. Another factor to mention is that all nuts have to be fastened with a right amount of torque (quite often, car manufacturers mention the right amount of torque to fasten lug nuts). In this case, the load will be distributed evenly and lug nuts will not experience excessive wearing.
