Using an air impact wrench can be frequently preferred by mechanics over hand tools to save on time. But using an air impact wrench can damage the component being repaired to your car to such a degree that it may never be the same again. An air impact wrench, sometimes called a mechanical torque wrench or eletric wrench, is a powerful industrial strength tool. Unfortunately, when damaged by misuse or mishandling, they can also be rendered ineffective. In addition, improper use or abuse of these power tools may also cause some serious injury or even death.


First, what exactly are torque wrenches? They are a type of wrench that have both positive and negative ends. The negative side of the wrench contains a needle-like protrusion which, upon applying pressure to it, increases the length of the bolt. The positive side of the wrench extends a short length of the bolt, which is then quickly gripped by the "patient" side of the wrench and rapidly expanded to produce tighter and longer bolts. The positive pressure required for this operation comes from the compressed air stored in the wrench's reservoir. The compressed air feeds into the open end of the bolt, which expands until it is totally covered by the expanding needle.

So how are they increasingly popular? Because they are highly portable - specifically, because they are less likely to be tethered to a surface than electric wrenches. They are very convenient for car repair work because they are battery operated and require no electricity to operate. Additionally, they are much more ergonomically pleasing than cordless electric impact wrenches.

The air impact wrench works by using a thin needle attached to a long, flexible tube. This tube, which may be long enough to go from floor to ceiling or may be wide enough to cover the entire bolt, is used by the operator to manually tighten nuts and bolts. It uses compressed air to expand the needle tip so that the user can increase the length of the bolt. They are similar to an electrical screwdriver except that it requires no electricity to operate. Instead, the user pumps air into the system using a hand pump or, if using a hand-held tool, uses a breath tube or aerosol bottle.

Most manufacturers advise against using air impact wrenches in certain circumstances, such as when installing metal screws. The reason for this is that they use a very low torque, and can literally rip the threads out of the threading. Although the tool may be useful for loosening stripped bolts, they are not appropriate for installing non-threaded hardware. However, most cordless home mechanics have no problems tightening stripped screws, which accounts for the increasing use of these tools. Many times, mechanics also use air impact wrenches to install cable wires, since the torque on these is typically much lower than that required to install high-torque screws.

Some air impact wrenches are small enough to fit into a pocket and are perfect for mobile technicians who work from vehicles. The air compressor portability of these tools makes them highly valuable for maintenance workers. Cordless mechanics can easily carry the portability of one of these tools while on the road, and they can perform maintenance work anywhere there is an electrical outlet available. This portability allows them to perform routine maintenance work in any location, including at construction sites, homes and garages, and even at the office.

If you purchase an air impact wrench that does not include a portability adapter, then you have a two-point power tool that requires its own electrical power source to operate. The majority of these tools provide all of the power that is needed to tighten nuts and bolts, but there are models available that only require the use of a battery to operate. The battery power will enable the user to operate the tool from either a full-automatic or a simple step-on mode. A two-position switch on the adapter allows the user to switch from a full-automatic operation mode to a step-on mode, which is useful for someone who may need to tighten bolts while working in a tight area.
