When it comes to tightening or loosening bolts and screws, a few different tools can get the job done. Actually, It depends on the size and shape of the bolt or screw and how tight it is; you might need an impact wrench or torque wrench.
Are you wondering about the difference between an impact and a torque wrench? Both are important tools for mechanics, but they serve different purposes. Read on to learn more about how each tool works and when it should be used.
You may be surprised to find a time and place for both tools in your toolbox!
How do impact wrenches and torque wrenches work?
A handy impact wrench delivers a sharp, powerful blow to loosen stuck bolts or nuts. It uses a hammering action to generate high levels of torque, which is the force needed to turn an object.
Impact wrenches are accessible in both corded and cordless models, and they come in a variety of sizes to accommodate different projects.
A torque wrench will help you apply the correct torque to a bolt or nut. It measures the amount of force applied to the object, then stops when the desired torque level is reached. It ensures the bolt or nut is tightened correctly without being over-tightened and damaging.
Torque wrenches are available in both digital and analog models, and they come in a variety of shapes to accommodate different jobs.
Advantages of impact wrench
- Easier to use than a torque wrench; can be used with one hand
- It can generate more torque than a torque wrench
- Can able to quickly removed tighten and rusted nuts and bolt
- You can work for long periods without any fatigue
Disadvantages of impact wrench
- More expensive than a torque wrench
- It requires more maintenance
Advantages of a torque wrench:
- It can be used to apply a specific level of torque to a bolt or screw
- Can be calibrated for accurate readings
- Often less expensive than an impact wrench
- It offers you more accuracy and control
Disadvantages of a torque wrench:
- It cannot generate as much torque as an impact wrench
Impact Wrench vs Torque Wrench – detailed comparison
Two types of wrenches are commonly used in mechanics: the impact wrench and the torque wrench. While both of these tools are designed to tighten or loosen bolts, they each have their own unique advantages and disadvantages. Here is a comparison of the two types of wrenches:
Operating system
The impact wrench is the faster of the two options, as it uses a hammering action to loosen or tighten bolts. On the other hand, a torque wrench measures the amount of force being applied to an object.
Durability
An impact wrench’s and torque wrench’s durability is important to consider when making a purchase. Impact wrenches are more durable than torque wrenches, as they can handle more wear and tear.
However, if proper care is taken, both tools can last for many years.
Torque and Speed
When it comes to torque, an impact wrench can generate more than a torque wrench. However, this also makes the impact wrench more challenging to control, which can lead to stripping the bolt or nut. This makes it perfect for use when speed is essential, such as when changing a tire.
The torque wrench, on the other hand, applies a controlled amount of torque to a bolt, making it less likely to strip. This makes it the preferred option for delicate operations, such as when working on electronic equipment. However, the torque wrench is typically slower than an impact wrench.
Price
If you are looking for a quality and consequential impact wrench, you can expect to pay around $100. On the other hand, you can expect to pay closer to $50 for a quality torque wrench. Although the impact wrench is more expensive, it is also more durable and can generate more torque.
Therefore, the impact wrench is a fast and powerful tool, and the torque wrench is a precise and controlled tool.
Size and Weight
An impact wrench is typically larger and heavier than a torque wrench. Torque wrenches are available in various sizes to accommodate different applications.
The weight of an impact wrench is typically more significant than the weight of a torque wrench. This is because impact wrenches have more power and are able to generate more torque.
Noise
When it comes to noise, an impact wrench can be noisier than a torque wrench. This is because impact wrenches have more power and are able to generate more torque. Additionally, the hammering action can be pretty loud, which can be uncomfortable for some users.
Maintenance
- Impact wrench: may require more maintenance than a torque wrench
- Torque wrench: typically requires less maintenance than an impact wrench
Impact Wrench vs Torque Wrench – Comparison Table
| Impact Wrench | Torque Wrench | |
|---|---|---|
| Tool type | Power tool | Hand tool |
| Power | High torque | Produce less torque |
| Precision | Less accuracy | More accuracy |
| Control | Less control | More control |
| Power source | Corded, cordless, compressed | Manual |
| Working period | Suitable for long-term works | Long-term work can cause excessive fatigue on your hand |
| Noise | Produce noise | noiseless |
| Price | Expensive | Reasonable |
| Size | Large power tool | Compact and small tool |

When should you use an impact wrench?
An impact wrench is a handy and powerful tool that can loosen and tighten bolts quickly and easily. However, it is essential to use this tool correctly to avoid damaging the bolt or nut.
When using an impact wrench, always start with the lowest setting and gradually increase the torque until the bolt loosens. It is also important to keep the tool well-oiled and clean, as debris can cause it to slip and damage the surfaces it comes into contact with.
With proper care and use, an impact wrench can be a valuable addition to any home garage or workshop.
When should you use a torque wrench?
A torque wrench is a tool that is used to apply a particular amount of force to a nut or bolt. This is essential because it makes sure that the nut or bolt is tightened to the correct level, which helps to prevent damage to the item being assembled.
Torque wrenches can be used for various purposes, including assembling furniture, tightening automotive parts, and even assembling bicycles. Generally, it is important to use a torque wrench when working with delicate items or when precise measurements are required.
However, there are some situations use a torque wrench is not necessary. For example, if you tighten a few screws on a piece of wood, you probably don’t need to use a torque wrench.
Can you use a torque wrench to tighten lug nuts?
A torque wrench is a vital tool for anyone working in their car. It applies a specific amount of torque to a bolt or nut, which is necessary to ensure that it is tight enough without being overtightened. This is especially important with lug nuts, as overtightening can cause damage to the wheel or even the studs themselves.
While it is possible to use a torque wrench to tighten lug nuts, it is generally unnecessary. Most lug nuts can be tightened by hand using a simple socket wrench. However, if you are unsure of the correct amount of torque to apply or are working with sensitive components, then using a torque wrench is the best way to ensure that you don’t cause any damage.
Conclusion
An impact wrench is better if you look for a fast and powerful tool. However, a torque wrench is better if you look for a precise and controlled tool.
Additionally, the price of an impact wrench is typically higher than the price of a torque wrench. Before purchasing, it is crucial to consider the project you are working on and the specific requirements of the task at hand.
