FAQs About Impact Wrenches

United Rentals is the right place to find used impact wrenches for sale. When you need to remove rusted or stuck bolts or lug nuts, an impact wrench is what you need. Impact wrenches are typically powered by compressed air, though electric versions are available, and they use rotational directional force to tighten or loosen large bolts and lug nuts. Although impact wrenches are widely used in the automotive industry for vehicle assembly and changing tires, they can also be used in heavy equipment assembly, machine tool manufacturing and construction projects. United Rentals carries brands like Dewalt, Makita and others to ensure you get a top-quality used impact wrench. For more information on impact wrenches for sale, see our listings above.

FAQs
How much torque do you need in an impact wrench?

The torque you need depends on your task; there are no one-size-fits-all air impact wrenches for sale. For example, an impact wrench will need at least 500 ft-lbs. of torque to remove lug nuts on most vehicles. However, lug nuts and bolts that are rusted may require a higher amount of torque. If you work in the rail or semi-truck business, you will likely need at least 1,600 ft-lbs. of torque output.

What size impact wrench do I need?

The most commonly used impact wrench sizes are ½-inch, 3/8-inch and ¼-inch, and they are suitable for most household projects. However, in a profession requiring more power, such as construction, ¾-inch and 1-inch wrenches are the better choice.

Are electric impact wrenches as good as air-powered wrenches?

Electric impact wrenches are convenient, portable and great for working in hard-to-reach places. However, unless you have multiple batteries, you may run out of juice before the job is done. Air impact wrenches, or pneumatic wrenches, are ideal for jobs where you need massive torque. Plus, they are not as bottom-heavy as their electric counterparts, as they do not require a battery, and with fewer components, they are easier to repair when something goes awry.
