Mechanics typically use air-powered impact wrenches, also known as pneumatic impact wrenches. These types of impact wrenches are powered by compressed air and are commonly used in automotive and industrial settings. They are known for their high power, durability, and versatility, making them well-suited for heavy-duty tasks such as removing and tightening lug nuts on cars, trucks, and other vehicles.
Air-powered impact wrenches are available in a range of sizes and styles, including in-line, right-angle, and butterfly designs. They typically have a square drive that accepts sockets and can produce high torque output, up to around 700ft-lbs. They are often preferred by mechanics because they are lightweight, durable, and easy to maintain.
There are also cordless and corded impact wrenches that are also used by mechanics but their popularity is less than the air powered one due to their lower torque output and less durability.
What size impact wrench do mechanics use?
Mechanics typically use a range of impact wrench sizes, depending on the task at hand. For automotive tasks, the most common size of impact wrench used by mechanics is a 1/2″ drive. This size is suitable for most standard automotive applications, such as removing and tightening lug nuts on cars, trucks, and other vehicles. A 1/2″ drive impact wrench can produce torque output up to around 700ft-lbs.
For larger vehicles and heavy-duty tasks, mechanics may use a 3/4″ drive impact wrench, which can produce higher torque output, typically around 1000ft-lbs. These larger impact wrenches are designed for use on heavy-duty trucks, buses, and construction equipment.
There are also smaller impact wrenches available, such as 1/4″ and 3/8″ drive impact wrenches, which are suitable for lighter tasks and working in tight spaces.
It’s important to note that the size of the impact wrench is not only determined by its drive size, but also by its design, power source, and other factors that can also affect the torque output. The best size of impact wrench for a particular task will depend on the specific requirements of that task, such as the size and type of fastener, and the accessibility of the work area.
Can I use an impact driver for mechanics?
An impact driver can be used by mechanics in some cases, but it is not typically the primary tool for automotive or heavy-duty tasks. Impact drivers are designed to deliver high rotational force, which is ideal for driving screws and other fasteners into wood, drywall, and other materials. They typically have a hexagonal chuck that accepts drill and driver bits.
While an impact driver can be used to remove or tighten fasteners, it is not designed for heavy-duty tasks that require high torque output such as removing lug nuts from a car wheel. Impact drivers are not designed to handle the same level of stress and wear as an impact wrench, and may not be able to withstand the demands of heavy-duty tasks such as those found in automotive and industrial settings.
It is better to use a proper impact wrench for heavy-duty tasks such as removing and tightening lug nuts on a car or for use in industrial settings, while an impact driver is a great tool for precision works and tasks that require delicacy.
