Torque Wrench: Which is the best of 2021?
oday you will know which are the best torque wrench models that can be found on the market.
When tightening the screws on a car or bicycle wheel, it is important that the ideal force is used. If it is too strong, the screw may be damaged. If it is too weak, the wheel may come loose.
We will show you the differences between the main products available and what you should pay attention to before making your purchase. So, keep reading to know all the characteristics of a torque wrench.
First, the most important
- There are 3 types of torque wrenches: digital, snap and rod. Let’s look at each one in detail.
- The torque is measured in Newton Meters (Nm). It is a unit of measurement that takes distance, weight and rotation into account.
- The tool is also known as a torque wrench. In this complete Buying Guide you will learn about all the details of it.
Best torque wrenches: Our favorites
We will now present the best torque wrench models. To reach this ranking, we take into account the main characteristics of the product. In this classification, we evaluated tools of three types: snap, stick and digital. Check out:
- Snap torque wrench with ratchet – MTX
- Dipstick wrench – Waft
- Electronic digital torque wrench with adapter – Gross
- Snap torque wrench – Waft
If you are one of those people who like to get their hands dirty and not rely on mechanics for minor adjustments, the torque wrench can be a great help.
If you decided to buy a torque wrench, but you are in doubt if it really is the product you need, rest assured. In this Guide, we will present the main advantages and what you should keep an eye on before buying.
What is the torque wrench?
Torque wrench is a tool widely used by mechanics. This equipment serves to tighten nuts and bolts.
In general, a torque wrench is shaped like a metal rod. On one side, there is a hole, in which is inserted a key and also an extender. On the other side, there is the grip.
The function of the torque wrench is to finish tightening a screw, as well as indicating whether that screw needs more tightening to remain firm.
Did you know that torque is a physics-related term that refers to the forces that produce rotation in a given body?
Torque is thus the result of the force applied to an object, which is capable of making it rotate around an axis or point.
What are the advantages of the torque wrench?
Anyone with a car, motorcycle or bicycle knows that tightening wheel nuts and bolts is not always simple. With a torque wrench, this activity is easier. In addition, the tool ensures that adequate torque is given to the screw to be fitted.
A torque wrench serves to finish the tightening of screws and nuts, allowing the adjustment to be more precise and efficient.
If there is excessive torque, the part may break. If, on the contrary, the torque is less than ideal, the wheel may even come loose. This is precisely the main advantage of a torque wrench: measuring the torque (rotation force) of the screw, allowing the adjustments to be extremely precise.
How to use a torque wrench?
As we already said, the torquimeter has as its main function to show if it is necessary to tighten more or less a screw, so that there is no damage to the part being fixed.
With this in mind, the units of measurement used for the torque wrench to work are as follows:
- Nm: Newton Metro
- Kgf. m: Kilogram-force Meter
- Lbf. In: Pound- force Inch
The meter at the base of the tool shows the units of measurement. To find out the maximum torque values, you can use the tables developed by the manufacturers.
After finding out which values to adopt, assemble the torque wrench with the extender and the socket wrench. At each twist of the torque wrench, pressure is inserted or removed.
In this video from the TOOLSWORLD channel, you can see how this tool works.
What is the difference between snap, stick or digital torque wrench?
When you buy a torque wrench, you will come across three different types: snap, stick and digital. Check out the characteristics of each one of them:
Snap torque wrench
In this version, you can set the desired torque using a button, which makes this adjustment automatically.
When force is applied to this tool, an internal system builds up pressure on a spring mechanically. As soon as the programmed point is reached, a click informs that the torque has been reached.
Dipstick torque wrench
In this type of torque wrench, you follow the gradual increase in torque on a ruler attached to the tool. As soon as the desired value is reached, the user must stop applying force to the torque wrench.
Digital torque wrench
With the digital torque wrench, the desired torque must be programmed before use. After executing the movement, you must wait for the beep. This signal will be emitted as soon as the programmed value is reached. From there the movement must cease.
Torque meters cost between R $ 40 and R $ 300. Prices may vary according to the type of torque wrench. Digital-type models, in general, are more expensive. Those of the rod type are cheaper.
In the middle of the price are snap torque wrenches. They have the best value for money.
Where to buy?
To buy a torque wrench, you should look for stores that sell mechanics and auto products. One example is the Car Market.
On the internet, there are also many options available. Several types and models can be found in retail stores such as Amazon.
We emphasize that buying online you usually find the best deals and you don’t even have to leave home.
Purchasing criteria: Factors for comparing torque wrench models
When buying, analyze all the details. By doing this, your money will be used well and you will not regret it. So, when you choose which torque wrench to take home, consider the following points:
- Material of manufacture and comfort
- Ideal type
Below you will understand the importance of analyzing each of these criteria. Keep reading until the end, we are close to receiving all the information so you can finalize your purchase.
Before buying, evaluate the use of the torque wrench and check if the chosen model reaches the torque that will be necessary for your activity.
The main models have torque ranging between 40 and 210 NM. Due to this wide variation, defining your need is essential to not buy the wrong model.
Workshops use torque wrenches with maximum torque. If the use is domestic, an intermediate torque wrench may be sufficient.
Material of manufacture and comfort
One point that must be noted is the quality of the manufacturing material. If the product has been made with durable material, the tool life will be longer.
Remember that this is equipment that will need to be applied with force. Therefore, the torque wrench must be resistant.
In addition, it is important that there is comfort in handling it. Make sure the cable is anatomical. A rubberized coating can guarantee extra comfort when using the tool.
Another important observation is to analyze the inch of the torque wrench. The socket is the fundamental part of this tool.
It is common to find 1/2 and 3/8 inch torque wrenches, but these measurements may vary. Some models may have more types of fitting, a considerable advantage. Make sure you choose the right model for your need.
This is certainly the most important criterion that must be taken into account. Define which type of torque wrench is ideal for your need. As we already said, there are three types: snap, stick and digital.
The digital is more expensive, but it has important advantages, such as electronic torque adjustment. This feature can save you time and is especially suitable for those who do not have so much experience.
The dipstick torque wrench is the cheapest. The entire system depends on the observation of who is using the device. Those who have more experience can do better with this type.
The snap torque wrench has an intermediate price. As the name says, a snap informs you that the desired torque has been reached. Both experienced and less accustomed users can see advantages in this model.
