Pneumatic impact wrench as a choice for the garage
If stationary use of the tool in the garage is expected, then auto mechanics prefer pneumohawk. The correct model can only be selected according to parameters.
Pay attention to the impact mechanism of a pneumatic impact wrench in the first place. It helps to loosen a stuck or rusted nut
Takes about 5 seconds for the impact wrench to work on one piece of hardware. The tool is in demand in garages, tire changers, auto repair shops, and other places where there is a need. The impact mechanism helps with large metal parts. Reverse power makes it easier for you to unscrew and tighten nuts with an impact wrench.
Black sockets are a better choice for impact tools
Best screwdriver set for electricians
Tip! It is best to choose black heads for your impact wrench. They are made of hardened steel that withstands the stresses better. If there is no impact function, you can go for the classic sockets in white.
The impact mechanism allows you to tighten the hardware with maximum force. No need for a manual overtightening torque wrench after the impact wrench. If there is no impact function, the person will have to perform a test re-tightening of the hardware by hand with wrenches.
Another important parameter is the rotor speed. Not to be confused with the torque, which determines the power. The rotational speed of an impact function air ratchet increases its power, but it has more of an effect on how fast you can work. High-rev models with a maximum torque of up to 8,000 lb. rpm are considered professional. It is the right choice for jobs with high volume of work.
Important! Small fasteners with a high torque may break threads if not used correctly.
The torque is the parameter that determines the power. If a weak impact wrench is used during operation, the nuts will not tighten properly. fasteners will loosen under load over time. The choice of pneumatic tools with a greater power than the recommended torque could overstress the thread. Over-tightened hardware will eventually collapse.
A professional impact wrench can have an output torque of up to 10000 Nm
Tire fitting stations and car repair shops use pneumatic impact tools with a minimum torque of 100 Nm. For domestic use it is better to choose less powerful models. If you need to choose a blowtorch for trucks, large agricultural machinery, the preference is given to the impact models with a large torque, for example, from 5000 to 10000 Nm.
The power of the impact wrench depends on the spindle size. The higher the torque, the larger the assembly. For example, an inch size spindle is necessary for metal fasteners with a thread diameter of 25 to 35 mm, and a 1.5 in. spindle is sufficient for 35 to 50 mm.
Carrying out the choice of pneumatic nutrunner, you need to make sure that the compressor compatibility, otherwise the tool will quickly fail. The optimal setting is when the operating pressure of the compressed air in the compressor tank is 2 bar higher than the air pressure of the pneumatic tool. Compressor capacity should be 1.3 times the airflow rate of an impact wrench.
In the video tips to help you choose a successful pneumohawk wrench:
How an air screwdriver works
The tool is connected to an air compressor or compressed air line via a coupling. When the trigger of the impact wrench is pulled, compressed air begins to flow into the wrench through the hose, causing the rotor of the tool to rotate and driving the spindle. The reverse function, i.e. the ability to switch the movement in reverse, makes it possible not only to screw in but also to unscrew fasteners.
- Straight blowgun wrenchesFormally designed with a handy gun shape in which the cartridge rotation axis is parallel to the motor axis of motion, providing high torque values;
- Angle impact wrenchesThese models have a spindle rotation axis that is perpendicular to the motor’s operating axis. They have a low maximum torque and are great for hard-to-reach jobs.
Features of air screwdrivers
When selecting a pneumatic wrench there are a number of features to consider:
- The torque of the impact wrenchThis characteristic directly affects the power of the tool, i.e. the power to tighten and unscrew. Measured in meters/newtonne. Bear in mind that the higher the index, the more powerful the compressor needs to be. Pay very close attention to this factor when choosing a tool. too much torque can break threads, and too little torque can cause a threaded joint to “loosen. Screwdrivers with torques between 30 and 3000 Nm are available on the market. Models with torque from 1500 to 3000 Nm are good for big fixings, and models with torque from 100 Nm are good for mounting and demounting of rims;
- wrench seat squareThe higher the torque, the larger the seat square. Pneumatic wrenches with ½ square drive are common for garage work. There are also powerful models with a 1-inch square footage;
- Wrench air consumptionIn order for your air wrench to work productively and correctly, it must be compatible with the air compressor you are using: air consumption and working pressure. Compressor operating pressure is preferably 2 bar higher than the tool’s operating pressure, and the capacity. higher by 20 to 30 percent;
- The weight of the impact wrench also influences performance. A too heavy wrench will make your hand fatigue, and a lighter tool will twist harder at a higher torque. The medium weight composite air wrench is the best choice. The weight of the impact wrench also depends on the type of impact mechanism, the lightest of which is the Twin Hammer.
- Torque regulator at the wrenchTo adjust the maximum torque;
- Impact wrench with reversing actionTo not only tighten, but also unscrew fasteners;
- Kit that includes an impact wrenchSave time and money by buying an impact wrench as part of a kit with all related consumables and accessories. That can be interchangeable heads, hex wrench, extension cord, etc;
- The presence of the impact wrench rubber pads and anatomical handles will make the process of work more comfortable, especially in cold seasons.

Impact wrench types
Wrenches can be divided into straight wrenches and cant wrenches.
Straight pneumatic wrenches Usually pistol-shaped and easy to hold in horizontal position. Their chuck rotation axis is parallel to the motor’s movement axis, which ensures high torque values.
In angle wrenches Spindle rotation axis is perpendicular to the motor axis, which makes it suitable for problematic or heavily soiled nuts. These models are especially in demand for work in tight and hard-to-reach places. These wrenches generally have a low torque rating.
A distinction is made between impact and nonimpact wrenches.
Impact wrenches Great for fastener assembly and disassembly where less force is needed or for sensitive fasteners that require precision and accuracy. These tools do not break threads.
Impact wrench Plows a series of rapid, tangential blows. It starts out with long strokes, but goes to shorter strokes closer to tightening. It is at the end where the final force is required for a strong connection.
Impact wrench is the wrench of choice for unscrewing old and rusted connections, for installing and dismantling larger bolt connections.
Important! Impact wrenches need to use particular impact sockets (they are usually black), t.к. conventional wrenches can simply burst.
What type of air screwdriver to choose for the garage
