An impact wrench is a tool that can be found in a toolbox and that provide leverage to a user. When a person squeeze the trigger of an impact wrench, the impact wrench applies force to a bolt with which the person is working such that the bolt that is being used breaks free from its position within the object being used. Furthermore, using an impact wrench can prevent a person from potentially hurting their knuckles, as well as prevent a person from having to spend many hour using a breaker bar to loosen those bolts.
An impact wrench may be a tool that is used in a variety of situations, and a person that is aware of the capabilities of such a tool may be able to recognize in what scenarios it can be of the most benefit to a user.
Common Practical Uses for an Impact Wrench
1. Automobile Repair and Lug Nuts
For example, in the field of automobile repair, a lug nut is often specified to be tightened to a certain specification. That specification is often one that a standard wrench would take longer to achieve, especially due to the effect of road salt and heat upon those lug nuts.
As a result of using an impact wrench with these lug nuts, a person may be able to remove those lug nuts in just seconds, as opposed to the many minute that may otherwise be required with conventional tools. Furthermore, these short bursts of torque can help to avoid rounding the lug nut with the wrench.
2. Deep Engine Areas
Another scenario in which an impact wrench is often useful is in those deep areas of an engine.
In these deep areas, the bolts that are to be loosened are often behind the engine. As a result, a person’s hand may not have enough clearance to utilize a ratchet wrench set to those bolts. However, an impact wrench does not require as much room to function; it only requires a few degree of rotation of those bolts to loosen them.
Mechanics who work on older models of trucks often find this to be especially useful; it may take an individual mechanic up to forty minutes to remove a single bolt. Yet, using an impact wrench, that same mechanic can remove the bolt in under ten seconds.
3. Heavy Equipment Maintenance
Another scenario in which an impact wrench is useful is for the maintenance of heavy equipment.
For instance, many brands of heavy equipment utilize massive pins and bolts to attach specific component of that heavy equipment. These bolts are often torqued to over one thousand foot-pound of torque when the equipment is manufactured. It can be difficult for a person to loosen these bolts when using only their muscle; they may even become injured.
However, using an impact wrench with the appropriate anvil and power supply, these manufacturer-made bolts can be loosened and removed from those heavy equipment components.
4. Construction Frameworks
Another use of an impact wrench is by construction crew who are constructing steel frameworks. In these frameworks, bolts are often embedded into the ground to which the steel frameworks will be attached.
These anchor bolts require a great deal of torque to be set into the ground; hence, workers utilize cordless impact wrenches to set these bolts. Additionally, an impact wrench allows carpenters to drive large lag screw into the timber structures; both of these construction scenarios require the strength of an impact wrench to enable the construction crews to work at the same rate and to remain in sync with the other construction workers on the site.
Another scenario in which an impact wrench is often useful is in the home by mechanics who are working on the suspension of a vehicle.
The suspension components that are often rusted in place with time require a great deal of force to be loosened by hand. Furthermore, a person has to avoid using their body weight on a cheater pipe to loosen these suspension component. The ability of an impact wrench to deliver sharp jolts to these components that loosen the rust without the need to use one’s body is one of the reasons that these tool are in high use by do-it-yourselfers.
5. Boat Engine and Propeller Maintenance
In addition to the scenarios described above, another area in which an impact wrench is often useful is within the maintenance of boats. The stainless steel fasteners on the engines of a boat can become seized up due to the corrosive element of the water. Additionally, the location of a propeller nut may make it difficult for a person to use a breaker bar to loosen it.
A compact cordless wrench can be utilized in this scenario; it does not matter in which direction a person set the wrench into the propeller nut. An impact wrench is also useful in the process of winterizing the outboard motor of boats that will be stored for the winter months.
6. Industrial Pipeline Construction
Another scenario in which an impact wrench may be useful is within the construction of industrial pipelines.
When industrial pipefitters are connecting two large metal component of a pipeline, they often use bolts to secure those components. These bolts must be torqued to a specific amount; an impact wrench is useful in these scenarios because the impact wrench will stop when it encounters the stretch limit of a bolt, which allows those pipefitters to feel when the bolts are secured proper.
7. Vintage Machinery Restoration
Another scenario in which an impact wrench may be useful is with restoration projects of vintage machinery.
Many of these vintage machines contain bolts that have been in place for decades. An impact wrench will help to loosen the rust that often forms between these components that have not moved in many year. A person must use the lowest setting for the impact wrench when first applying it to a vintage machine’s components.
Yet, as the impact wrench loosens the rust, the person can increase the setting of the wrench to loosen even the oldest of rusted component.
Farmers also find the usefulness of an impact wrench when they are repairing their farm machinery. For instance, if a farm machinery like a combine harvests crops during the season, if that machinery breaks down, the farmer need to perform repairs as soon as possible.
If that farmer utilizes an impact wrench to replace a component like a drive sprocket, the farmer will save time that would have taken thirty minutes to perform with a wrench alone. Furthermore, since an impact wrench is portable, the farmer can travel with that tool to the farm upon which the machinery is performing; if the machinery is powered by batteries, the farmer can also utilize the impact wrench within remote area of the farm.
8. Lighting Grids and Concert Stages
Another scenario in which an impact wrench is useful is in the setting up of lighting grids or concert stage.
The bolts that hold these structure together must be secured to allow for safety in these lighting grids, yet not so secured that the crews for those lighting grids are unable to disassemble the components after the concerts are over. Thus, these lighting crews utilize impact wrenches with adjustable torque settings to hold the components in place. Additionally, the speed at which an impact wrench can operate is another benefit for these crew who are breaking down the lighting grids after the concerts.
One final scenario in which an impact wrench may be helpful is in the field of search and rescue operation. Emergency crews who attend the scene of an automobile crash often utilize impact wrenches in their tool kit. These tools are often used to remove the bolts and suspension components from the cars that are involved in the crash, and those components may have to be separated from those cars in order to extract the passengers from the vehicles.
Each of these scenarios in which an impact wrench is often used shares a common theme: high torque, limited space, and time, or rusted components. An impact wrench is not a tool that can perform precision task; it is a great tool for breaking the rust between two components that have not been separated from each other in many years. Furthermore, while it is a potent tool, an impact wrench is not one that can replace a set of ratchets.
However, in the correct situation, an impact wrench can transform an otherwise impossible task into a routine task that can be performed with ease. The clatter that the tool make is an extra feature of the tool. Now that so many scenario in which an impact wrench is beneficial have been described, a person who is aware of these benefits will find opportunities to use an impact wrench in a variety of locations and application.
An impact wrench does not make a person a better mechanic; however, it does remove many of the physical barrier that stand in the way of a person who wishes to complete their repair projects. Thus, it is beneficial and a benefit worth considering by many individual.
