How Will You Choose the Best Digital Torque Wrench?
It’s not wise to go shopping for a digital torque wrench without knowing what features are important. That’s why we’ve curated the below pointers and we hope you will find a digital torque wrench that suits your specific needs. Check it out!
Accuracy
As you’re probably aware, applying the right amount of torque to bolts is critical in certain applications. If not properly tightened, engine head bolts can vibrate and cause components to go out of alignment, leading to leaks. With that said, accuracy is the key in your search for a digital torque wrench – the best models are accurate up to +/- 2% clockwise and +/- 3% anti-clockwise. You should go for one that has this minimum level of accuracy to avoid any problems occurring during use.
Torque Range
A lot of manufacturers offer digital torque wrenches in different sizes and with different magnitudes. Some have higher ranges compared with others, and this is obviously linked to the price. If you are only working on simple projects like bicycle maintenance or fixing a lawnmower for example, it would probably be wise to choose a product with a lower torque range since you don’t need a very big range to tighten anything up in those areas. For car repairs though, it would be smart to get yourself a tool that has at least a torque range of 150 foot pounds.
Measurement Units
While most digital torque wrenches will offer ft-lbs as the standard unit, you may also find other units manufacturers use. One such example of this is newer cars with European origins where instructions are either provided in kg-cm or Nm.
To ensure that your wrench gives you more accurate readings for whatever project it is you are taking on, make sure your tool has a number of different measurement units handy (such as when you need to go from ft-lb to kg-cm) since conversions can be quite tricky at times; otherwise if you’re working mostly on automotive part replacements, having ft-lbs and Nm available should be more than enough for all your needs.
Forward and Reverse Tensioning
One of the most common mistakes made with a torque wrench is to loosen nuts when it is set to operate in the clockwise position. This happens because turning a nut counterclockwise can give the appearance that it is becoming loose, when in fact it’s only becoming more firmly tightened! A good way to avoid this typical mishap is by using a ratcheting type wrench which allows you to quickly change between clockwise and counterclockwise orientations. These don’t typically come standard but are highly recommended as they give improved access and increase user confidence.
Readability of Scale
When it comes to reliability, digital torque wrenches are vastly superior to their analog counterparts because they have large, easy-to-read displays that allow you to immediately know what the current torque reading is without interrupting your workflow. Now, each individual product has different shading, text, and even menu options all over their display so if you’re having trouble with your eyesight, a digital display with larger text may be easier to read. And if you find yourself working in dimly lit areas like garages or workshops quite often, look for a digital display that is backlit to make sure you can still see everything clearly and accurately since we wouldn’t want anything to get confused.
Grip and Handle
Choosing the right torque wrench handle is crucial to using your tool correctly. Unlike a standard wrench or socket, you’ll want to find a handle that provides flexibility and isn’t too rough in your hands while also allowing it to move freely so you don’t have excess pressure while applying torque.
In order to prevent slipping of any kind, look for grips that are smooth but provide enough friction. Even something as small as a well-designed grip can make or break whether an individual will be able to use their tool effectively. So always take care when choosing this aspect of a digital torque wrench or else it can end up doing more harm than good.
Emergency Alert System
When looking for a digital torque wrench, you want to make sure that it alerts you as soon as you’ve reached the desired level of torque. Some models will alert users with an audible alarm or visual indicator on the digital display, while others let users know they have exceeded the set torque by use of a vibrating handle.
Some options even alert users before they have completely reached the desired level of torque – making it almost impossible not to get the job done fast and efficiently!
Angle Torque Measurement
Torque to yield bolts, most commonly used in the cylinder heads, require proper sequence, or sequence tightening. Failure to do so may lead to leaky or gummy seals. So having a digital torque wrench that allows you to apply torque and angle in one continuous motion will be a crucial money and time saving investment
Do I Need a Torque Wrench With Angle?
Depending on only torque reading when fastening a bolt isn’t enough. Most of the time due to mechanical error or false reading, you may leave the bolt vulnerable to disaster. Torque wrench with angle function eliminates such a problem with a single swoop. Both the torque reading and angle feedback ensures proper tension to the bolts.
Benefits of Using Digital Torque Wrench With Angle
Tightening nuts and bolts are prevalent in any repair or maintenance jobs. Whether it is in auto shop business or sophisticated engineering works, you need a solid tool to avoid over tightening. Digital torque wrenches with angle function are such tools that allow users the precise feedback in both audio and visual form.
That’s not all. It also takes out all of the guessing game when it comes to tightening bolts/nuts to specific requirements. We all have been there where we spent a lot of time with angle gauges and sharpies. That’s just to make sure we are in the right place and settings.
With a digital torque wrench with angle option you get all the functionality in one wrench. You don’t have to change equipment nor have you to swap different torque wrench for the specific operation. That’s how you speed up your work and increase overall productivity. You can’t have that with generic torque wrenches.
What Size Torque Wrench Should You Buy?
Its depends as per your needs. As we said earlier in our quick overview- torque wrench used for many purpose like change a tire, lug nuts, engine work, spark plugs, dirt bike and bicycle.
There are three most common size available on the market-
- 1/2 inch drive best for lug nuts and Wheel and large fasteners.

On the other hand, Digital torque wrenches have better functionality and various feedback systems with a slightly steep price tag. With just one digital torque wrench, you can potentially do all sorts of fastening tasks. One thing to keep in mind: you need to calibrate and keep an open eye when the battery runs out. Apart from that it’s a great choice for beginners and individuals who like faster work progress.
Does Digital Torque Wrench Need Calibration?
Most brand new digital torque wrench comes with factory calibrated sittings. You can also find the calibration details in the instruction manual. Even though this calibration is correct, you need to calibrate your wrench before any delicate fastening task. Some digital torque wrenches have automatic calibration systems otherwise you may need a wrench calibrator.
How Do You Calibrate a Digital Torque Wrench?
Like any torque wrenches you need to calibrate its settings for accurate output. The best part of calibrating a digital torque wrenches is it doesn’t need extra equipment. Most digital torque wrench manufactures embed the calibration option into the circuitry. It means you can self-calibrate the digital torque wrenches within a few seconds.
For the wrenches that don’t have a self-calibration system, you will need an external wrench calibrator or a torque checker. We will cover both methods to properly calibrate your digital torque wrench.
Digital torque wrench has a built in calibration system that allows the wrench to self-calibrate. This happens every time you turn on the power of the torque wrench. Make sure you leave the wrench on a flat surface and wait a few seconds. Your wrench should calibrate automatically. Read the instruction manual for other calibration methods if there are any.
The other way to check calibration is to test the torque through a torque checker. If calibration is off, then follow instructions in the manual to make adjustments. You can also use a traditional torque wrench with the digital one to see if the reading lines up.
Do you need to lubricate a digital torque wrench?
It is important to inspect the ratchet of a digital wrench periodically, wiped clean and oiled up if it shows signs of wear. Check that the screws holding the ratchet in place are tight, and that the ratchet turns smoothly when being used. The wrench handle shouldn’t have any lubricant on it.
What Does NM Mean on a Digital Torque Wrench?
NM or Newton Meter is a unit for measuring torque. In wrench operation, 1 NM denotes a specific amount of torque resulting from 1 newton force applied perpendicularly to the end of a 1 meter lever/rotational arm. To avoid detrition of bolts and any damage to auto parts, manufacturers recommend a certain amount of torque. Sometimes it is expressed in NM, sometimes in Ft-Lb (foot-pound) measurement. NM is a measurement in the SI System. 1 ft/lb. force is equivalent to 1.36 NM.
What Is the Limitation of a Torque Wrench?
While the torque wrench makes fastening work much easier and effortless, it has its limitations. With time and wear it may lose accuracy to read proper force. You need to make necessary calibrations to maintain proper accuracy. Another limitation can be the capability. Torque wrench has a specific limit of torque reading. If it’s 250 lb. torque wrench, it cannot read beyond that reading.
How Long Does Torque Wrench Last?
A well-maintained torque wrench lasts a very long time given usage under rated limit. Unless there are any manufacturing faults in the mechanical parts you won’t have any issue. Although, you may need to calibrate the torque every year or so to get accurate results. Compared to traditional wrenches, digital wrenches need more frequent calibration to operate properly.
