5 Best Impact Wrenches

An impact wrench is a tool used to make tightening and loosening tough bolts or nuts easier and more efficient. They reduce the effort and exertion of a user while delivering high torque output in a way that won’t damage bolts or nuts. An impact wrench can produce a much higher amount of force than a person can with their hands, without the need for additional leverage. This makes them ideal for hard to reach places or stubborn bolts.

Impact wrenches can be found in a variety of settings from auto shops to large construction projects and may sometimes be called air wrenches (as many of them are pneumatically powered), torque guns, or impactors. In addition to pneumatic power, they may also be powered via a direct electrical connection or a rechargeable battery.

We have reviewed the top 5 best impact wrenches on the market now, and we weighed all of the important factors to consider before you decide to purchase on for yourself.
