Torque Wrench vs Breaker Bar? Which One is Best?

The torque wrench and breaker bar are the most familiar tools in the automotive and mechanical industry. The function of these two tools is to properly tighten and loosen the nuts and bolts; though their work is something related, their features are very different.

Sometimes beginners and professionals become confused about their differences and work purposes. This article will help you to know more about torque wrenches and breaker bars. What are they used for, and what is the main difference between them?

So let’s get introduced to both tools before going into a detailed comparison.

What is a Torque Wrench?

Torque Wrench vs Breaker Bar

A torque wrench is an advanced-level automotive tool that is always used for maintenance and repair tasks. It is designed to be used for tightening purposes according to proper measurements.

The torque wrench is made of durable and sturdy materials. It can be easily handled. Whether you work on a small or large project, the torque wrench is the perfect choice for a specific torque.

What is a Breaker Bar?

Torque Wrench vs Breaker Bar

Breaker Bar is a well-known common tool in the automotive and mechanical industry. Many people know it as Power Bar. It is mainly used in the unbolting task, and if there is no need for accurate measurement, it can be used for tightening. Many people also use it to break extremely tight fasteners easily.

It has a long non-ratcheting bar, which can produce a lot of strength and torque. As a result, tightening and loosening work can be done much faster.

Torque Wrench vs Breaker Bar Detailed Comparison

In this part, we make a detailed comparison of these two tools and analyze the two tools part by part, which will help you know which tools are suitable for each purpose and which one will be perfect for your work. So let’s see.


First of all, if we compare the price, then we can see that the torque wrench is a bit more expensive than the breaker bar. There are many reasons for this, which we will see in the next, but one of the main reasons is that the torque wrench has many advanced level features, which is perfect in detailed work, due to which its price is a bit expensive.

On the other hand, the breaker bar is a common mechanical tool, and it is much more budget-friendly than a torque wrench in terms of the price range.

Smarter Picks

A torque wrench is a modern tool that has the capabilities to work at advanced levels. The torque wrench is the smart pick from these two tools options for accurate torque measurements to the nuts and bolts. It also has more next-level features starting from LED indicators, which further ensures the accuracy of the work.

On the other hand, the breaker bar is not a modern tool, but it will help you achieve faster performance by saving time. It does not have any kind of torque measurement mechanism, which allows you to work fast, but there is a possibility of over-tightening in the field of work.


There are multiple different models of torque wrench available for various works. That’s why you can find many types of torque wrench in the market according to your work. For example, some wrenches are click wrench, digital wrench, beam wrench, etc.

On the other hand, there are no various models or options of the breaker bar. That’s why you will not get a different choice of a breaker bar for your project.

Tightening and Loosening

The torque wrench is designed with an exact measurement mechanism, which can be used to properly tighten the nuts and bolts. However, many people mistakenly used it for loosening. That’s why there is a chance that it will be damaged by using it several times.

On the other hand, the breaker bar is the perfect choice for both tightening and loosening. It has a large handlebar, which helps you easily create pressure and loosen bolts effortlessly. It does not have any kind of measurement mechanism, so if measurements are not required in your torque work field, then the breaker bar is also an excellent choice for tightening for you.

Durability and Lifespan

Torque wrench and breaker bar are both made with high sturdy construction and durable aluminum, which can provide high strength torque for tightening and loosening effortlessly. Also, the two tools have to be maintained very carefully. It makes both tools last for a long time. Specially, After each use, try to store the torque wrench in a durable case.

So there is no difference between the two tools in terms of durability.

When to Use a Torque Wrench

Torque wrenches are indispensable in situations that require precise and controlled torque application. Consider using a torque wrench in the following scenarios:

1. Engine and Automotive Repairs

In automotive repair and maintenance, torque wrenches ensure that critical engine components, such as cylinder head bolts and spark plugs, are tightened to the manufacturer’s specifications.

2. Construction and Engineering

In construction and engineering projects, torque wrenches are used to tighten structural bolts, ensuring the stability and safety of buildings and structures.

3. Delicate Machinery Work

For delicate machinery work, where overtightening could damage sensitive components, torque wrenches provide the necessary control and accuracy.

4. Preventing Overtightening

When tightening fasteners that require specific torque values to prevent damage or ensure optimal performance, a torque wrench is essential.

When to Use a Breaker Bar

Breaker bars are best suited for tasks that require loosening or tightening fasteners with extra leverage and force. Consider using a breaker bar in the following situations:

1. Breaking Loose Stubborn Fasteners

When encountering tightly stuck or rusted nuts and bolts, a breaker bar’s longer handle provides increased torque, making it easier to break them loose.

2. High Torque Applications

In heavy-duty applications where significant force is required, a breaker bar’s leverage helps in applying torque comfortably and efficiently.

3. Working in Limited Spaces

In tight or cramped spaces where a torque wrench’s head cannot fit, a breaker bar’s long handle allows for torque application without the need for a full swing.

4. Avoiding Physical Strain

For tasks that demand substantial force, using a breaker bar can reduce physical strain and fatigue on the user.

Torque Wrench vs. Breaker Bar: Pros and Cons

Torque Wrench Pros:

  • Precise torque application with controlled tightening.
  • Ideal for automotive, construction, and delicate machinery work.
  • Ensures fasteners are tightened to the manufacturer’s specifications.
  • Reduces the risk of overtightening or under-tightening.

Torque Wrench Cons:

  • Not designed for breaking loose stubborn fasteners.
  • May not provide the necessary leverage for high-torque applications.

Breaker Bar Pros:

  • Provides extra leverage for breaking loose stubborn fasteners.
  • Suitable for high-torque applications.
  • Useful in tight spaces where a torque wrench may not fit.
  • Reduces physical strain when applying significant force.

FAQ: Frequently Asked Questions

Can a torque wrench be used as a breaker bar?

“No.” The torque wrench is specially designed for accurate tightening work, so you can’t use it for tightening and loosening purposes like a breaker bar.

Is the breaker bar the same as a torque wrench?

Though the breaker bar and the torque wrench functionality are slightly similar, there are still many differences. The main difference is that there is no torque measuring mechanism in the breaker bar, due to which if you use it for tightening purposes, you will not get accurate torque results. On the other hand, the torque wrench has a measuring mechanism. That’s why it is perfect for tightening.

Again the torque wrench is not designed for loosening, so you cannot use it for loosening, but the breaker bar is perfect for loosening.

Conclusion: Which one is best?

Torque wrench and breaker bar, both tools are perfect for two different work areas. If you are working on tightening and loosening nuts and bolts without any accurate measurements, then a breaker bar is an excellent choice for you.

On the other hand, if your job is tightening with accurate measurements, then the torque wrench is the ideal choice for you. In this case, you can not use the torque wrench in the field of loosening and loosening purpose; you will need a breaker bar. Lastly, we do not judge these two tools as alternatives to each other; both tools are essential for your mechanical work. That’s why I will suggest you keep both tools and use them as needed.
