You need the best torque wrench for lug nuts if you are planning to do your own motor vehicle maintenance.
The wheels get a lot of attention and with a good reason. Tightening lug nuts to the right pressure is a matter of life, and death!
Why you need to torque your lug nuts
If loose, the lugs will continue unthreading until they fall off. If too tight, you will damage the threads of the hub studs as well as the lug nuts themselves.
A wheel hub has threaded studs. On your rims, you will see four, five or six holes that match with the studs on the hub.
When you fit the wheel onto the hub, you should attach the lug nuts to the threaded studs and then tighten them with your torque wrench.

What size of torque wrench do I need for lug nuts?
Whether you want to use a click-type torque wrench, a beam wrench or a digital torque wrench for your wheels, size is everything!
By size, we mean a few things. For instance, the size of the head is paramount. Most of these wrenches come with a fixed square head.
The head holds the socket drive that goes on the lug nut so that you can tighten it. For most cars, ½-inch torque wrench is going to work just fine. For trucks, you would need something bigger, say, about 5/8 inches.
But size does not apply to the head and drive only. It also applies to the handle. Thus, most of the torque wrenches for car wheel lugs come with 18-inch handles.
Another thing you might want to consider alongside the size is the safety features. For this, you can get a torque wrench that comes with a spring loaded ball detent system on the fixed square head. This is going to prevent the socket from falling off the wrench when you are working on it.
The same thing as using an impact wrench on lug nuts, some will require you to use a torque wrench of 3/8-inches to tighten.
If you are really a DIY-er when it comes to maintaining your car, you should get yourself a full kit with different socket drives and adapters.
In most automotive garages, you will find that the torque wrench size they use most is ½-inch. For bikes, ¼-inch torque wrenches get most of the fasteners done.
How hard should lug nuts be torqued?
The question you might be asking here is: How many foot pounds should I torque for lug nuts?
You have to check the amount of force the fastener manufacturer requires you to use. No matter how qualified you are, do not tighten your lug nuts without knowing the force to apply.
Different cars require different torque levels for their wheel lugs. Overall, the torque requirement for wheel nuts is 110 to 120 Nm.
Here is a table to show you different lug nuts and the level of torque you should use on them:
| Car type/Model |
Lug Nut Torque Level |
| 2020 Ford Ranger |
100 ft-lb/135 Nm |
| Toyota Tundra |
85 to 150 ft-lb/115 to 203.4 Nm |
| Chevrolet Silverado 1500 |
90 ft-lb/140 Nm |
| Volkswagen SCIROCCO |
80 ft-lb/108.5 Nm |
| Nissan Almera |
81 ft-lb/ 110 Nm |
| Toyota Prius |
76 to 80 ft-lb/103 to 108.5 Nm |

These are a few cars and models that are popular in America. Whatever car or bike you have, check the user manual for the recommended torque levels for lug nuts. You can also check the manufacturer’s website or check in car forums.
Considerations when buying a torque wrench for lug nuts
If this is the first time for you to buy a torque wrench to maintain your car, you can find it challenging to choose the really best one.
There are so many types, and there are hundreds of brand names. With all of them claiming to bring the best, you need to do your due diligence well.
This guide is not just for mechanics. Even DIY-ers can use it to buy these tools for their car maintenance needs.
Here are a few factors to consider when you are buying a torque wrench for lug nuts:
Torque range
This is the most important consideration for a torque wrench. In the table that we have compiled above, you can see that some car lug nuts need to be torqued to more than 200 Nm.
The arm length
This is vital because it can affect how easily you store the wrench and how easily you use it to tighten the nuts.
For easier work, longer torque wrenches are better because you will need to apply minimal effort to tighten the lug nuts, especially for the manual torque wrenches.
However, also consider how you are going to store the wrench. It should not be too big because you need it to fit nicely in your car.
Before you can order a torque wrench, find out the recommended torque level for your car. You can then buy a wrench that has a torque rating higher than what your car manufacturer recommends.
If you have replaced the stock lug nuts with OEM nuts, check the manufacturer torque ratings for the lug nuts.
Once you know the torque level, you will know the torque range for the wrench that you will buy.
The drive design and sockets
The design of the torque wrench is vital. For instance, most of the wrenches come with fixed square head designs for holding the socket.
This is where the real design work comes in. It is best to look for a wrench that has a spring loaded ball detent design system. It is made that way to hold the socket tight, and prevent it from falling down.
Also, check the socket sizes that you need, again, guided by your lug nut sizes. Usually, these should be 17mm, 19mm, 21mm and 23mm. This is the size range for most car lug nuts.
When you are buying the wrench set, make sure it contains these socket drives. If you have two or more cars at home, do not assume that all of them have the same lug nut sizes.
Storage case
Always buy a torque wrench that has a strong plastic case for easier storage and transport. If you drop the case, the material will absorb most of the shock so it is possible that the wrench is not going to lose its calibration.
The storage case is going to make it easier to store your torque wrench in the trunk of your car. Again, this should not be too big as it can take too much space. Remember, the compartments in the trunk are small.
Torque wrench style
Next to torque range, this is another vital factor. If you run a garage where you repair cars, buses, trucks and other vehicles, well, you will need different types of lug wrenches. For big wheels, you can use pneumatic torque wrenches.
Pneumatic wrenches use air compressors for power. They are heavy-duty torque applicators that can have high torque levels of up to 47000 Nm. They are also used in the construction industry.
For small wheels such as cars, a click wrench will do just fine. You can also use a digital wrench if you do not want to deal with the shenanigans of setting up torque manually.
If you want the most accurate torque wrench in the market, you should get yourself a dial type torque wrench. These ones can be expensive to buy, but they are worth every dime you pay for them.
You might want a cheap, yet effective and super accurate wrench. Get the beam style torque wrench because it is easy to use and to keep accurate.
As long as the pointer stays on zero when you place it on a flat surface, the wrench is still in calibration.
Torque readout method
By torque readout, we mean the alert method that you get once you have torqued the fastener to the maximum.
Of course, many wrenches are designed to “fail” when you apply the set torque, so they cannot continue tightening. However, they should also give a form of alert.
Click wrenches give a click sound. Digital and electronic wrenches give a click, flash an LED light and give a buzzer.
If a torque style wrench gives a click sound only, you might not be able to use it in a noisy garage. You can easily miss the alert sound.
In noisy environments, a torque tool that flashes a light and fails to torque the fastener any further is best. For home use, manual torque wrenches will work just fine.
Explore all the types of wrenches keenly to see which one suits your needs in the best way. For your home needs, a simple click type of torque wrench is going to suit your needs.
The price
As with any other products, when you are buying a wrench, some are priced quite extravagantly while others are cheaper.
The best thing is that there is a wrench for every budget. However, you should never sacrifice features for the price. It is better to spend more money and get better features than the vice versa.
Check the accessories, if any, the wrench set comes with. The more the merrier. Get more value for money all the time.
Material
Most metal torque wrenches are made from chrome vanadium steel alloy. However, there are ABS wrenches. Avoid plastic wrenches because they cannot be used for heavy-duty tightening jobs.
Accuracy rating
If you find a torque wrench that has an accuracy rating of +/-2%, take it. Mostly, the accuracy of lug nut torque wrenches is within the +/-2% to +/-5% range. If it is a dual direction wrench, ensure the accuracy in the counterclockwise direction might be a bit low.
What torque wrench do I need for lug nuts?
Knowing the torque level you should apply on your lug nuts is one thing. Knowing the best torque wrench to use for the job is another thing.
So, do you need a click style, a digital/electronic wrench, manual wrench, beam or pneumatic torque wrench? That’s what we will find out here.
The most accurate torque wrench is the best for your car’s wheel lug nuts. To reiterate something that we already mentioned, the best size is ½ inch for the socket and at least 18 inches for the handle/length.
