When it comes time to tighten the lug nuts on the car's wheels or replace the spark plugs, it's necessary to ensure that the fittings are tightened to the manufacturer's specified torque level. This seems impossible if you are using a standard socket wrench, but a torque wrench is a specialized tool specifically made for this purpose.

The user can set the torque limit on the wrench in order to prevent over-tightening fasteners. Just keep in mind that a torque wrench is only used for tightening and should never be used for loosening, as this can result in the wrench becoming uncalibrated and may lead to problems in the future. Take a look at this list of top products to find the best torque wrench to add to your workshop or garage.

What to Look for in a Torque Wrench


There is a wide variety of torque wrench types due to manufacturer innovation over the years. To choose the best torque wrench for your garage, it's necessary to learn about the benefits and drawbacks of each type. The most popular styles of torque wrench include beam, deflecting beam, click, and digital torque wrenches.

  • Beam torque wrenches are basic tools that rely on the flex of the wrench to measure the torque. It has a long arm or beam that attaches to the head of the wrench, and there is a scale located near the end of the handle that indicates the amount of torque currently being applied.
  • Deflecting beam torque wrenches are essentially the same as beam torque wrenches in how they function with one major difference: A deflecting beam torque wrench has a secondary beam that runs behind the main arm of the tool. This secondary beam is known as a deflecting beam and it bends instead of the main arm bending, making the deflecting beam torque wrench more durable than a standard beam torque wrench.
  • Click torque wrenches are the most recognized in this tool category because they are the most commonly used. The torque level is easy to set by twisting the base of the handle to match up with the desired setting on the handle. These torque wrenches get their name from the audible click that the wrench makes when it reaches the set torque level, though it's important to note that most click torque wrenches do not have a limiter, so users need to stop applying force as soon as they hear the click to avoid over-tightening.
  • Digital torque wrenches are usually the most expensive choice, but they come pre-calibrated and display clear, precise readings on a digital screen, making them the easiest to read and use. Just keep in mind that the torque wrench runs on batteries and without power, it will not function properly, so keep it equipped with fresh batteries whenever possible.

Drive Size

The size of a torque wrench's drive determines the bits that can be used with the torque wrench. Standard torque wrench sizes include 1/4-inch, 3/8-inch, 1/2-inch, 3/4-inch, and 1-inch, though most DIYers won't need to use a wrench that is larger than 1/2-inch in size.

  • The 1/4-inch drives are the smallest option and these wrenches are really only used for working on small power tools or vehicles, like motorcycles, mopeds, and lawnmowers. However, these wrenches may be necessary for smaller fitting on a car or truck.
  • 3/8-inch drives are regularly used in automotive repair, especially when the user is working on the engine. Some spark plugs need to be tightened with a 3/8-inch drive, though most spark plugs need a 1/2-inch drive.
  • The 1/2-inch torque wrench drive is the most commonly used size. These torque wrenches are ideal for reinstalling lug nuts, replacing spark plugs, or tightening fasteners on the vehicle's suspension.
  • 3/4-inch to 1-inch drives aren't usually necessary for DIYers because these sizes are really only used on large vehicles like semi-trucks and construction vehicles.


The entire purpose of a torque wrench is to ensure that the nuts, bolts, and other fittings are tightened to the exact specified level of torque, so accuracy is one of the most important considerations when deciding on a torque wrench for the home garage. After all, over-tightening or under-tightening the lug nuts on the car could lead to problems when you are driving.

Typically, the torque wrench manufacturer will indicate the measured accuracy of the product based on a calibration test that is performed prior to the torque wrench being packaged, shipped, and sold. The calibration level usually has an accuracy rating of about ±4 percent, though there are superior torque wrenches with higher accuracy ratings (e.g., ±3 percent accuracy).

  • What is a torque wrench?

    Torque wrenches are commonly seen in automotive garages because there are many vehicle components that need to be tightened to a specific setting. Any tighter or looser could cause problems, so this specialized tool tightens the fittings to a measured level, allowing DIYers and professional automotive techs to be confident about the torque of each fitting.

  • How do you use a torque wrench?

    The method for using a torque wrench differs between the various types, but it's important to note that a torque wrench should never be used for loosening fittings, only tightening. In general, you can use a torque wrench by setting the torque level (if necessary), placing the drive bit on the fitting, and tightening to the appropriate torque level. You can use a torque wrench to tighten nuts, but never for loosening. Torque will be indicated differently depending on whether you are working with a digital torque wrench, a click torque wrench, or any of the other torque wrench types.

  • How does a torque wrench work?

    A torque wrench works differently depending on the type, but all torque wrenches are made to measure the current amount of torque on the target fitting and apply the right amount of torque to tighten the fitting to the ideal torque level.

  • How do you calibrate a torque wrench?

    Calibrating a torque wrench by yourself can take some time and patience, especially if you have never calibrated a torque wrench before. You can take a torque wrench to a local hardware store for calibration or gather the following items: A bench vise, a 20-pound weight, a measuring tape, and a thin rope or string that can hold at least 20 pounds. With these items on hand, follow the steps below to calibrate your torque wrench.

    1. Use the tape measure to measure the length of the torque wrench. Start from the square drive on the head and measure to the exact point on the handle where the user grips the wrench. Typically, there is a line on the handle to indicate this point.
    2. Take the torque wrench and put it into the bench vise. The torque wrench should be held in the bench vise by the square drive.
    3. Determine the torque setting by multiplying the length of the torque wrench (measured in step one) by 20.
    4. Hang the 20-pound weight from the handle of the torque wrench by looping the string through the weight and tying a knot. The string should be lined up with the mark on the handle.
    5. When the weight is in place, listen for a click. If the wrench clicks, lift the weight and move it slightly towards the head of the wrench. Hang the weight from the new position and listen for a click. Continue moving the weight towards the head of the wrench until it no longer clicks.
    6. If the wrench doesn't click the first time you put the weight on the handle, tighten the spring in the wrench, then lift the weight and lower it again to test for a click.
    7. If you are successful, this should indicate a precise area on the torque wrench where the weight can hang without any clicks.
    8. Measure the length of the torque wrench again, but this time take the measurement from the square drive to the point where the weight is now hanging. Multiply the measured length by 20.
    9. Use the formula Ta = Ts x (D1/D2) to calculate the applied torque of the wrench. Ta equals applied torque. Ts equals torque setting. D1 equals the distance measured in step 1. D2 equals the distance measured in step 8.
    10. Using this number, you can multiply your intended torque by the difference to give you the correct torque setting for your specific torque wrench.
