Do you need clarification about the difference between a breaker bar and a torque wrench and help to select which tool best fits your task?
Having the appropriate tools is essential when working on vehicles or other machinery. Breaker bars and torque wrenches are two standard tools used for this task. However, they serve different functions.
Each tool is engineered with its own specific goal in mind. Breaker bars are specifically designed to break free tight, frozen and rusted fasteners; torque wrenches feature mechanisms which exert exact amounts of torque onto fasteners.
These tools are convenient when overtightening is not an option, such as working with spark plugs, lug nuts, engine building or assembly.
What Is A Breaker Bar?
In automobile repair, maintenance, and other sectors, breaker bars remove tight bolts and nuts that wrenches can’t loosen. Its architecture is simple: a robust handle with a male square socket at one end that may stay fixed or swivel within a specified range of angles. It doesn’t damage anything; it loosens screws.
Types of Breaker Bars
There are two main types of breaker bars available in the market:
1. Hinge Handle Breaker Bar
This type of breaker bar has a hinge in the middle of the handle, which allows the user to adjust the angle of the socket. It is ideal for use in tight spaces where a regular breaker bar cannot be used.
2. Ratchet Breaker Bar
This type of breaker bar has a ratcheting mechanism that allows the user to rotate the socket in one direction. It is ideal when the user needs to apply torque to the bolt or nut.
How to use a Breaker bar?
Utilizing a breaker bar is straightforward and user-friendly. After selecting an appropriate socket size for loosening a bolt or nut, attach it to the male square socket on the end of the breaker bar, and apply force through its handle – rotating this way will loosen any remaining fasteners or nuts that remain tightened down on it.
Can We Use a Breaker Bar for Tightening Bolts and Nuts?
Breaker bars are typically designed for loosening tight bolts or nuts, though they can also be used for tightening them if necessary. It should be noted, however, that final tightening should only be accomplished with a breaker bar as this could apply too much torque and cause irreparable thread damage.
Which is the Best Breaker Bar in the Market?
There are various brands of breaker bars on the market, each boasting its own set of features and benefits. Some popular ones are Craftsman, Snap-on and Stanley; your individual needs and budget will determine the most suitable breaker bar option.
Breaker Bar Safety Issues
When using a breaker bar, it is imperative to take certain safety precautions to avoid injury. Wearing gloves and eye protection may prevent injuries from flying debris, and ensure the bar is upright and secure to reduce slipperiness or any potential for damage to surrounding areas. In addition, users should always comply with manufacturer instructions when using their tool for its intended use.
Pros:
- It rotates 230 degrees, making it perfect for a variety of tasks
- Extended 40 inches in length, making it more convenient and powerful
Cons:
- The head is a bit too loose for my liking
What Is A Torque Wrench?
Torque wrenches are an indispensable tool for mechanics and DIY enthusiasts, used for tightening nuts or bolts to their recommended torque in their user’s manual. Torque wrenches allow users to tighten bolts or nuts at specific torque settings to ensure they do not loose too quickly. When this set torque is reached, a click sound will typically sound.
Types of Torque Wrench
1. Click Type Torque Wrenches
This type of torque wrench is the most popular and commonly used. It has a clicking mechanism that indicates when the desired torque setting is reached.
2. Split Beam Torque Wrenches
This torque wrench has no clicking mechanism like the click-type wrenches. Instead, it uses a visual indicator to show when the desired torque is reached.
3. Digital Torque Wrenches
This type of torque wrench has a digital display that shows the torque setting and indicates when the desired torque is reached.
4. Slip Type Torque Wrenches
This type of torque wrench is designed to slip when the desired torque is reached. It is commonly used in applications where over-tightening could cause damage.
5. Intelligent Torque Wrenches
This type of torque wrench is the most advanced and comes with features like Bluetooth connectivity, data logging, and torque-angle readings.
How to use a Torque Wrench?
Using a torque wrench is easy and requires a few simple steps. Here is a step-by-step guide:
- Determine the torque specification for the bolt or nut you want to tighten. This information can be found in the user’s manual.
- Adjust the torque wrench to the desired torque setting.
- Place the torque wrench on the bolt or nut and tighten it until you hear a click or see the visual indicator that indicates the desired torque is reached.
- Repeat the process for all the bolts or nuts that need to be tightened.
Is it Possible to use a Torque Wrench in Reverse?
No, using a torque wrench in reverse is not advised. Torque wrenches are intended to tighten bolts or nuts clockwise only using one in this manner could damage its precision and accuracy.
Which is the Best Torque Wrench in the Market?
Various torque wrench brands on the market offer different features and benefits to meet specific user needs and budget constraints. Finding the ideal torque wrench depends entirely upon individual preferences and circumstances.

- Conversion scale on the body of the tool is for more convenience
Cons:
- Audible click is not very loud
Breaker Bar Vs Torque Wrench Differences
1. Differences in Design
A breaker bar is a long, straight bar equipped with a square drive at its tip; on the other hand, torque wrenches have an elaborate ratcheting mechanism and gauge to measure the torque applied. Breaker bars are easy-to-use devices, while torque wrenches require calibration for accurate results.
2. Apply Force
Breaker bars apply maximum Force against stubborn or rusted bolts, while torque wrenches tighten them at a specific torque setting without overtightening them.
3. Types of Fasteners
Breaker bars are typically employed on larger bolts or fasteners that require considerable Force to loosen, while torque wrenches are ideal for more delicate fasteners requiring precise torque settings.
4. Accuracy
Torque wrenches are intended to deliver precise torque settings, while breaker bars tend to be used more for brute force tasks that don’t require as much precision.
5. Cost Differences
Breaker bars tend to be cheaper than torque wrenches yet provide a different level of precision and accuracy. Torque wrenches may become quite pricey if you require professional-grade models.
