The Best Digital Torque Wrench Options for DIYers and Pros


A torque wrench is a specialized tool that is regularly used in automotive repair to ensure that the parts of the vehicle are not under- or overtightened. Mechanical tasks are easier and more precise with digital torque wrenches, which provide you with a digital display that shows the exact amount of torque in use. Some of these devices are equipped with warning signs—including flashing lights, sounds, or vibrations—that indicate when you have reached the desired torque.

Digital torque wrenches are precalibrated. Some allow you to preset multiple torque levels so you can quickly shift from one everyday task to another with the push of a button. Ahead, see some of the best digital torque wrenches reviewed for efficacy, quality, and overall value.

What to Consider When Choosing the Best Digital Torque Wrench

Don’t go shopping before you know which features are most important in a digital torque wrench. Deciding how much or how little these attributes matter to you will help you find the right digital torque wrench for your needs.

Accuracy and Measurement Units

One of the most important things you pay attention to as you’re shopping for a digital torque wrench is accuracy. If a wrench is not accurate, you may under- or overtighten it when you use it, which can cause fasteners to break or come loose during the machine’s operation. Most digital torque wrenches are precalibrated to an accuracy rating of about ±4 percent, though more and less accurate digital torque wrenches are certainly out there.

Torque is measured in inch-pounds or foot-pounds, where an inch-pound is 1 pound of force applied to 1 inch of distance from the pivot point of the torque wrench. A foot-pound is 1 pound of force applied to 1 foot of distance from the pivot point.

Torque Range

If a digital torque wrench’s range is too low, the types of jobs you can perform with it are limited. A torque wrench with a range maximum that falls below 100 foot-pounds is ideal for simple tasks, like working on a lawnmower or bicycle. However, wrenches with a lower torque range aren’t much use for most automotive and mechanical torque wrench applications.

Some digital torque wrenches have a very wide torque range, with some reaching a maximum of 1,000 foot-pounds of force. However, most digital torque wrenches have a moderate range that reaches up to 150 foot-pounds, which is more than enough torque to tighten lug nuts on your car.

Multidirectional Tensioning

Multidirectional tensioning, or ratcheting, allows the user to quickly change the direction of the wrench in order to measure torque in both the clockwise and counterclockwise orientation. A torque wrench with this feature gives the user better access than one that only operates in the clockwise direction. You won’t see torque wrenches with this feature often because they should never be used for loosening nuts. This is because a nut may initially be seized when you try to loosen it and when the torque wrench applies force, the nut can jolt forward and cause the wrench to require recalibration.

Handle Comfort

Most torque wrenches come with either a rubberized plastic handle or a steel handle with a raised grip. The upside of rubber grips is they are comfortable and reduce hand fatigue; metal handles give you better control over the wrench. Whichever one you decide on, the handle is an important aspect to keep in mind when looking for a new torque wrench.

When using the digital torque wrench for long stretches at a time, it’s a good idea to prioritize comfort and choose an ergonomic grip that does not make your hand cramp. What’s most important is that the digital torque wrench you select has a handle that you can grip without your hand slipping. You must be able to stop the motion of the wrench handle quickly when you reach the desired level of torque so you don’t overtighten the nut.

Scale Readability 

Digital torque wrenches have a big advantage over other types of torque wrenches when it comes to their scale reliability because they have prominent displays that show the current torque reading. However, the size, shading, text, and even menu options on the digital display vary among individual products.

If you have difficulty reading small text, a digital torque wrench with a large easy-to-read display may be a good way to go. If you’re working in dim lighting conditions, such as a garage or workshop, look for a digital screen with backlighting. Just remember to keep the batteries in your digital torque wrench charged, or you won’t be able to read the scale at all.

Alert Features 

A terrific feature to look for in a digital torque wrench is an alert that will let you know when you have reached the inch-pounds or foot-pounds of torque you desire. Some products alert users via a blinking LED light or a visual indicator on the digital screen, and others via handle vibration, an audible alarm, or a combination of two or more of these signals. Visual indicators on the digital display may even signal how far you have exceeded the optimal torque. This emergency alert feature makes tightening fasteners while you work almost foolproof because the wrench is telling you to stop.

Auto Shutdown

Digital torque wrenches are powered by batteries that operate the digital screen, the internal mechanics of the measurement device, and the alert systems. The problem with batteries, of course, is that they can run out of energy. When this happens, you need to either recharge the batteries or replace them before you can resume working.

To help extend the battery life of your digital torque wrench, some models will automatically shut off after several minutes of inactivity. Given how many times you may put down and pick up your torque wrench while working on your car without turning it off, this auto-shutdown feature will probably save you a significant amount of battery life.

Storage Case

Digital torque wrenches are sensitive devices whose accuracy can be affected if they are knocked against anything or dropped on the ground. To protect the device and reduce the number of times it must be recalibrated, look for a digital torque wrench that comes with a storage case.

Digital torque wrench cases are usually made of hard, durable plastic that protects the tool but is also lightweight and easy to carry. For additional protection and security, invest in a torque wrench case that has interior padding and a lockable clasp.

The Advantages of Owning a Digital Torque Wrench

A digital torque wrench is an upgrade over a regular torque wrench for several reasons: first, a digital device uses built-in alerts—including sound, light, and even vibration—to prevent you from overtightening the fasteners being worked on.

The digital display on a digital torque wrench is also much easier to read than the physical display on a regular torque wrench; many digital products even have backlit screens that can be read in the dark. Another great benefit of owning a digital torque wrench is that it is precalibrated. When you do have to calibrate a digital wrench, it’s easier to do so than it is with a regular torque wrench because the digital display provides a more accurate measurement.

  • Digital torque wrenches have built-in alert systems to notify you when you reach the optimal torque.
  • The digital display is much easier to use for getting an accurate reading of your applied torque.
  • Digital torque wrenches come precalibrated and are easier to calibrate than a regular torque wrench.


Below are helpful answers to some of the most common questions about torque wrenches.

Q: What is a digital torque wrench?

A digital torque wrench is a precalibrated torque wrench that displays the torque output on a digital screen. When you reach the required amount of torque, the wrench will notify you with a buzz, beep, vibration, light, or some combination of these alarms so you do not overtighten the fastener.

Q: How do I know if my torque wrench is accurate?

To know whether your torque wrench is accurate, you can test the torque reading on the digital display against a known torque output. Here’s how:

  1. Secure the square drive of the wrench in a bench vise, allowing the rest of the wrench to move freely.
  2. Measure the distance between the square drive on the head of the wrench and the point on the handle where you grip.
  3. Multiply the distance measured in Step 2 by 20 to find the inch-pounds torque wrench setting.
  4. Hang a 20-pound weight from a thin string at the exact place on the handle of the torque wrench where you would normally grip (often marked with a line).
  5. If the readout on the digital display matches your inch-pound findings in Step 3, your digital torque wrench is accurate.
  6. If it is not accurate, you can calibrate it yourself or take it to an experienced professional to calibrate it for you

Q: How do you calibrate a torque wrench?

You can calibrate a torque wrench using a bench vise, a 20-pound weight, a thin rope or string (capable of holding at least 20 pounds), and a measuring tape.

  1. Measure the length of the torque wrench from the square drive on the head to the exact point on the handle where you grip the wrench. This line is commonly marked already on a torque wrench, so you shouldn’t have to estimate based on your average usage.
  2. Put the square drive of the torque wrench into the vise and tighten it.
  3. Multiply the measurement you took in Step 1 by 20 to find the inch-pounds setting you require for the torque wrench.
  4. Tie a loop through the 20-pound weight with the string and hang it from the end of the handle where you took your first measurement.
  5. Check the readout on the digital display, which should equal the inch-pounds measurement that you set in Step 3. If it does not match, move the weight toward the head or end of the digital torque wrench until the inch-pound readout properly lines up with what you have entered.
  6. Measure the length of the torque wrench from the square drive to the point where the weight is hanging, and multiply this finding by 20 pounds.
  7. With the information you have gathered, you can now calculate the applied torque of the wrench using the formula Ta = Ts x (D1/D2). “Ta” is applied torque. “Ts” stands for torque setting. “D1” is the distance measured in Step 1, and “D2” is the distance measured in Step 8.
  8. Using this number, you can multiply your intended torque by the difference to get the correct torque setting for your specific torque wrench.

Q: How often should I calibrate my digital torque wrench?

You should calibrate your digital torque wrench at least once a year; however if you use it regularly, you may want to calibrate it two or more times per year.
