When a nut underneath your hood gets loose, you need a way to quickly fasten it before you run into issues.
Nuts and bolts do not only play a part in keeping everything in your car connected.
These are hardware items found in lawnmowers, on your bicycle, and in many other systems.
If you run into a situation where you need to fasten these nuts and bolts, you’re going to need a torque wrench.
When you need to loosen these nuts, you will also find yourself in need of these tools.
Your regular wrench might work for some basic tasks, but without a torque system, you may find it hard to loosen some hardware. You may also find that the wrench slips easily.
The best torque wrench for engine work gives you a more advanced grip while also ensuring less pressure is needed to turn your hardware.

What To Consider When Choosing The Best Torque Wrench
You’ve decided to get your hands on a torque wrench, but now you feel unsure about which one to buy.
Learning the best torque wrench for cars is means understanding how to read the technical specifications.
Additionally, note that what is the best wrench for one person may not necessarily be such a great option for another.
In this section, we help you understand what to look for when buying a torque wrench.
Consider each of these factors to ensure the wrench you buy will work effectively while also maximizing the value you get for the money spent.
Handle And Wrench Grip
The grip really is everything when it comes to safety while using a torque wrench.
Even the best torque wrench for engine work may end up a poor choice if it lacks a good grip.
With this in mind, always look at the grip offered by the torque wrench.
Start by considering the handle.
In terms of safety, the handle tells you a lot.
A handle that is constructed with your grip in mind will essentially ensure there is a lower risk of slipping.
If a wrench slips out of your hand when it is being used, it puts both your car and yourself at risk.
The torque wrench can damage the interior parts of your car, leading to a significant expense on your side.
It can also slip in such a way that it comes into contact with your skin – this may lead to a broken finger or cut skin.
While considering your own grip is important, take note of the other factors that come into play too.
The grip of the wrench’s teeth is important too.
You don’t want it to slip off a nut while you are trying to loosen or fasten it.
Ratchet Function
In many cases, you may find that a torque wrench is used for fastening nuts.
There are few scenarios where people use these wrenches as a way to loosen nuts – but, at the same time, you may run into such a situation.
Being able to use the same tool for fastening and loosening can be beneficial. It also means there is no need for an additional expense.
If you are looking to have both functions in one system, then you should consider a torque wrench with a ratcheting function.
These wrenches have a switch that allows you to change the position of the tool. Note that if you are using a ratchet function, do not be too harsh on the nut.
If you push too hard, it may cause the nut to jolt in a forward direction.
When this happens, you may find that your torque wrench needs to be recalibrated before using it again.
Readability Of Torque Scale
A torque wrench will have a specific torque scale that can be used while fastening a nut.
During this process, you do not want to apply too much pressure to the nut.
At the same time, applying insufficient pressure means you won’t be able to fasten the nut all the way.
This is where the torque scale comes in.
There are a few torque wrenches that do not come with any scale.
A slip-style torque wrench is a good example.
These wrenches are often not used to assist in working with an engine.
Instead, you want to ensure the wrench can give you an easy-to-read indication of the current torque scale.
Digital torque wrenches are becoming quite popular.
These wrenches usually provide a pre-calibrated system and make it much easier to read the current torque scale.
A click-style torque wrench is also a great option since there is an engraving used as an indication for the current torque scale.
Torque Range
Sometimes, you need just a small torque range to fasten a nut – but there are times where a more significant range is needed.
If the torque range is limited, then you will find the wrench cannot be used for certain functions.
Always consider the specific tasks that you will use the torque wrench for.
A small range is ideal if you will only be using the torque wrench on something like a bicycle.
These torque wrenches may also work in cases where you have a need to fix a lawnmower.
For engine work, however, you may need to consider an option with a bigger torque range.
Wrench Accuracy
You don’t want to have a nut disconnecting while you are driving.
At the same time, when fastening a nut, you do not want to over-tighten it.
This can cause a section of your engine to break in some cases.
Simple mistakes can cost you.
This is why the accuracy of a wrench is yet another factor to consider.
A torque range should have the best accuracy you can find with engine work; the better the accuracy, the lower the risks.
Calibration of the wrench should offer accuracy of 4% or lower. If you can find a wrench with a 3% or lower accuracy, then that’s even better.
Size Of The Drive
One last thing we highly recommend you look at before picking a torque wrench is the drive size. This is a term that refers to the bits that can be used to help work with nuts.
There are a few standard sizes.
These include:
- ¼ inch
- 3/8 inch
- ½ inch
- 3/5 4inch
- 1 inch
In most cases, you’ll need a ½ inch or smaller.
The specific application you will be using the torque wrench for should be considered, however.
A ¼ inch drive size is ideal for lawnmowers and motorcycles.
These can also be good for bicycles.
When it comes to sparking plugs and repair work on an engine, then you will likely need a 3/8-inch drive size instead.
For most people, a ½-inch drive size is ideal.
This drive gives you a good balance.
It’s great for use in cars and can even be used on the suspension.
Final Words
A torque wrench is useful in more than just the automobile industry.
Having one of these wrenches at home comes in handy when nuts and bolts need fixing on your engine, a bike, or even the lawnmower.
There are a few factors that should be taken into consideration when looking at the best torque wrench for cars or other automobile factors.
Follow the tips in this guide and consider the options we shared to help you find the perfect match for your toolbox.
