Torque wrenches are an integral part of an automotive mechanic's tool kit, allowing nuts and bolts to be tightened to exact specifications. Their unique construction, consisting of threaded fasteners, allow users to apply the correct amount of force, load, and tension to tighten correctly without damaging your engine or other internal parts.
Torque wrenches use a ratchet mechanism combined with a set of gears to rotate the wrench handle backward while the fastener stays in one place, tightening and loosening bolts to the correct torque. The best torque wrenches make accurate torque readings (expressed as foot-pounds), have a durable construction, and come in four available sizes: 1/4-inch drive, 3/8-inch drive, 1/2-inch drive, and 3/4-inch drive. Check out our recommendations on the best torque wrenches.

Why Buy a Torque Wrench
- Get accurate measurements. Since many automotive parts require a proper level of torque to be safe and secure, a torque wrench offers a precise way to get the right torque specs the first time. This makes it easy to hit the manufacturer recommended levels each and every time. This is especially important for different parts like lug nuts.
- Preserve components. The main reason torque wrenches are so important is a matter of safety. Too much or too little torque on parts is dangerous. In addition to the danger of parts coming loose, too much torque can also damage parts.
Types of Torque Wrenches
Click-Type
Click-type torque wrenches are the most popular type of torque wrench. They use a clicking mechanism to indicate that the correct amount of torque has been applied. More or less torque can be applied within a specified range, with gauges indicating force expressed in inch-pounds, foot-pounds, or Newton meters. Simply pull the click wrench to the desired torque setting and a small level inside the wrench locks as soon as it makes contact with the inside of the wrench handle wall, letting you know when it is time to release.
Today, click-type torque wrenches come with manually adjustable settings or in digital form, each with ratchet heads available in four sizes: 1/4-inch drive, 3/8-inch drive, 1/2-inch drive, and 3/4-inch drive.
Beam
Consider beam wrenches the visual version of a torque wrench. Beam wrenches use a torque scale and digital pointer to indicate the amount of torque being given. As the wrench is rotated, the beam moves the indicator. These typically come with very large gauge faces for easy readings, albeit offering a bit less accuracy as everything is done by eye versus torque wrenches. Expect beam wrenches to be cheaper than torque wrenches as well.
Electronic
Electronic torque wrenches substitute the click-type mechanism for digital readouts to let you know when the desired amount of torque has been reached. Consider electronic torque wrenches a hybrid of click-type and beam style torque wrenches, merging a readout and an automatic notification.
Note: electronic torque wrenches come at a higher cost than click-type and beam wrenches. If you are looking for convenience and accuracy, electronic torque wrenches are hard to beat.

Key Features
Size and Torque Range
Nuts and bolts used in automotive work come in all shapes and sizes. Each of them requires a different torque range, expressed in pound-feet or inch-pounds.
Torque wrenches come in four sizes: 1/4-inch drive, 3/8-inch drive, 1/2-inch drive, and 3/4-inch drive. The larger the size, the greater the amount of torque applied.
The 1/4-inch drive torque wrenches work with tiny nuts and bolts with a max torque range of 50 to 250-inch pounds. The 3/8-inch drive ones work with the most common nut and bolt sizes used in mechanics shops everywhere, working a range from 15 to 75 foot-pounds. The 1/2-inch drive and 3/4-inch drive torque wrenches are used for larger internal components such as engine mounts, transmission mounts, and center-lug wheels with a range of 30 foot-pounds or greater.
Accuracy
As a general rule, opt for torque wrenches obtaining certification guaranteeing an accuracy of 5 percent or better. To earn bonus points, look for an ISO 6789 accuracy certification, which guarantees an accuracy rating of plus or minus 4 percent for up to 25,000 cycles. Even the slightest deviation from the intended amount of torque applied can cause some engine parts to break.
Note, your torque wrenches accuracy may deviate if dropped or experienced heavy wear and tear. As a result, it is very important to calibrate it from time to time and store it properly to ensure accuracy. There are many resources available online with step-by-step instructions on how to calibrate a torque wrench.
Range
Also referred to as torque range, our recommendation is to look for a torque wrench that offers 150-foot pounds or more of range, which is more than adequate in tightening automotive lug nuts. Some are even capable of 500 foot-pounds of force, which is necessary for more intensive applications. Anything below 100 foot-pounds is best reserved for light work (e.g. bicycles and scooters)
Comfort and Auxiliary Features
Exerting a heavy amount of pressure under hoods or in dark areas places a premium on ergonomics. If a torque wrench is not optimized for comfort, wrist or joint pain can result. Many of today's torque wrenches come with rubberized, knurled handles or steel handles with a raised grip. Some also come with flexible heads (as much as 15 degrees), which allow them to sneak under places that are hard to reach.
Other auxiliary features focus on visibility. Many torque wrenches come equipped with LED lights that illuminate a certain color as soon as the required force is reached. Some even emit alarm sounds.
Do not forget readability. Scales should be very easy to read. A quick glance should be enough to read the current torque level. Click-type torque and beam wrenches use handle-mounted scales to indicate the torque amount. Digital torque wrenches use a digital scale, which is the most straightforward of them all. Only slip-style torque wrenches do not use scales.
Storage
Do not underestimate a good carrying case for your torque wrench. Repeated wear and tear or repeated knocking in your tool kit could cause it to lose sensitivity and accuracy over time. Look for torque wrenches with a protective storage case that contains plenty of padding.
Other Considerations
- Accuracy. In order to get the best results, a torque wrench needs to be as accurate as possible. Accuracy partly depends on the calibration and precision of the instrument itself. For example, the beam needs to be aligned correctly on a beam torque wrench. Accuracy also depends on the readout of the wrench. Better results are common with electronic and click-type wrenches because of the digital readout and/or sound notification.
- Comfort. Since all torque wrenches require force from the user to work, comfort and usability are two important considerations in terms of overall ergonomics. The size, length, and grip of the shaft, for example, influence the overall comfort of the wrench. More leverage makes it easier to apply higher amounts of torque without extra effort. A grip makes it easier to maintain a secure hold on the wrench, even if your hands are slippery from engine oil or automotive grease.
- Ratchet Design. A ratcheting head is a simple way to maintain a precise level of torque as you increase the overall amount. Beam torque wrenches, for example, force you to apply the torque all at once in a single rotation. Wrenches with a ratchet, however, hold the current level of torque as you rotate the handle to apply more force. A ratchet tends to be common with electronic and click-type torque wrenches. Other good design traits include steel construction, a reversible ratchet function, quick release buttons, and a good chrome finish.
Best Torque Wrenches Reviews & Recommendations 2021
The CDI Torque Micrometer Wrench is an absolute workhorse. It offers 1/2-inch drive power to pull torque from 30 to 250-foot pounds. A calibrated dual scale and spring-loaded positive lock with a pull-down lock ring make it very easy to set up and use. Quick-release buttons also make socket retention easy.
Our only knock on the CDI Torque Micrometer Wrench is that it has a plastic handle. We would have preferred a knurled, rubberized handle for a more comfortable grip and feel. However, if you are looking for an excellent beginner torque wrench, then the CDI Torque Micrometer Wrench is hard to beat.
This Tekton 1/2-inch drive click-type torque wrench offers a steady performance in more ways than one. It leads with an all-steel construction, reversible ratchet head for clockwise torque measurement, and an easy-to-read dual-range scale (foot-pounds and newton-meters) that looks good in all lighting conditions. Like the CDI Torque Micrometer Wrench, accuracy is very good (+/- 4 percent tolerance).
As mentioned, 1/2-inch drive is the most recommended torque wrench type for most automotive applications. Kudos for the Tekton’s included storage case, which helps it avoid knocks in your tool kit that could cause it to lose its calibration over time.
Remove the guesswork from the amount of torque force you need with the ACDelco digital torque wrench fitted with an LCD screen. Simply input your desired torque and start working on the bolt until the built-in audible buzzer lets you know when the pre-set torque is achieved.
The wrench has 2 percent accuracy in the clockwise direction. As you adjust the torque, you will appreciate the anti-slip grip of the handle. It’s easy to calibrate the scale and you can change out the display from foot-pounds to other units of measurements, including inch-pounds, newton-meters, and kilogram-centimeters. Lastly, this torque wrench is very lightweight and runs on four AAA batteries.
However, it has a pretty average torque range for an electronic torque wrench, which only stands at 4-99 foot-pounds. Also, the screen doesn’t have a backlit display, and that would make it hard to use in a dimly lit room.
This metal handle torque wrench from CDI comes in a variety of sizes and styles, making it easier to choose exactly what you need. The sizes range from 3/8 inch to 1 inch. The torque range for the 3/8-inch option is 10 to 100 foot pounds. It is dual scale and calibrated dual direction. The lock is spring-loaded and it has an easy-to-read design. The torque wrench weighs three pounds. CDI is known for its high-quality tools and commitment to durability, so as you would expect, this product comes with a limited warranty to ensure it is free from defects or manufacturing issues.
This is an expensive torque wrench, and you get what you pay for. It is highly accurate, hefty, and does the job well. It also comes with a certification of calibration, giving you peace of mind about its authenticity.
However, due to its price, this is not something you want to casually buy. There have also been issues with the adjusting collar being too loose.
Less expensive than other torque wrenches on the market, the eTORK model has a 1/2-inch drive and a range of 50 to 250 foot pounds. It is accurate to +/-3 percent in a clockwise direction. It can be used in both a clockwise and counterclockwise direction. It is made from hardened alloy steel for durability and a long life. It also has a large diameter soft-grip handle, making it user-friendly. The package it comes in also includes a calibration certificate and an owner’s manual.
However, this is not a torque wrench you can self-calibrate if that is something you need to do. The locking mechanism also is not the most user-friendly. But overall, for the price, this is an exceptional torque wrench able to handle large jobs.
This torque wrench has a nickel and chrome finish and a wider, ergonomic grip. It has a ½-inch drive with a longer length to reach difficult places. You can also set the torque wrench for repeated work. The adjustable knob on it reduces spring tension, making it easier to set the torque. It weighs just over 4 pounds and it only tightens clockwise, not counterclockwise. It has a 20 to 250 foot pound range. Like most others on the market, it is accurate to 4 percent. Overall, this is a dependable and sturdy wrench.
However, it only does clockwise work, so if you want more flexibility, this isn’t the product. The box it comes to store it in is a little large, and the snapping noise is quiet at a low torque setting, making it harder to hear. For the price, though, this has excellent value.
This torque wrench from Gearwrench falls in about the mid-range of price, leaning towards more expensive than most others. It has a ½-inch drive and has an astounding accuracy rate of 2 percent clockwise and 3 percent counterclockwise. It has a 72-tooth ratchet mechanism and a 5-inch swing arc, giving you greater flexibility while at work.
One of the biggest benefits of this product, however, is its “target torque alert.” When you approach the target torque, a vibrating handle, buzzer, and LED light will indicate the target is reached. This protects you from accidentally breaking the wrench. It has a chrome finish and it weighs 3 pounds. It has a range of 25 to 250 foot pounds. Its electronic display shows the torque reading even after you remove it.
It does require batteries to operate, though, and it tends to go through them quickly. It is easier to go over torque than other wrenches, so you have to be careful as you operate it.
This torque wrench has a range of 20 to 160 foot pounds and a ½-inch drive. It works both clockwise and counterclockwise. The ratchet head has three-sided bite teeth, protecting it against slipping. It has a 3 percent margin for calibration, which is slightly higher than the industry standard. Its body is made to protect against corrosion and rust, allowing it to last longer. The body is made of hardened chromium vanadium steel alloy and it has a slightly wider grip section. The locking device is also designed to be very user-friendly. It is cheaper than other torque wrenches and weighs just over 4 pounds.
This is ideal for home use, but possibly not for professional mechanics, as the range isn’t large. Also, the readings for torque don’t always line up when locked.
The Gearwrench electronic torque wrench offers tons of digital features in a super slim profile. Along with its 72-tooth ratchet mechanism and 5-degree swing arc to cut into tight spaces, there are several bells and whistles to let you know when the correct amount of torque has been applied. These include an audible alarm, vibrating handle, and solid LED light.
Accuracy with the Gearwrench electronic torque wrench is on point, clocking in to within a +/- 2 percent accuracy (CW) and +/-3 percent accuracy (CCW)
Additionally, the Gearwrench electronic torque wrench offers five torque measurement units, making it easy to understand no matter what region you are in. Measurements are expressed in newton-meters, foot-pounds, inch-pounds, kilogram-force meters, and kilogram-force per square centimeter.
We especially like its ergonomically focused rubber handle and slim carrying case, helping to minimize drops out on the garage floor which could mess with accuracy and constant recalibration over time.
The Capri Tools torque wrench is a nice value option and well-rounded across the board. It's a 1/2-inch drive click-type that guarantees +/- 4 percent accuracy and adheres to several industry accreditations that vouch for it (e.g. ASME B107.300-2010 and ISO 6789:2003 standards).
This wrench’s high contrast torque scale uses a laser engraved handle that shows measurements in foot-pounds and newton meters. A knurled rubber handle also provides a steady grip, eliminating hand fatigue with repeated use.
Tips
- If you only need one torque wrench, use a 1/2-inch drive size, which offers enough torqueing power for most automotive applications such as adjusting brake rotors or tightening fasteners on major powertrain components.
- Go for torque wrenches that have protective cases. Repeated knocks against your toolbox or tool drawer could cause calibration to knock and become out of whack. Look to calibrate your torque wrench at least once a year or as needed based on usage. It can be done on your own or with an experienced mechanic.
- Torque wrench thread can become clogged with debris and rust over time. Be sure to clean them before your torque a fastener down or risk under or overextending the amount of torque. Even a -/+ 2 percent deviation could make a difference.
- Be sure to use the proper torque as recommended by the parts manufacturer.
FAQS
Q: What is a torque wrench?
A torque wrench allows a nut or bolt to be tightened to a specific torque level per the manufacturer's recommendations. There are five main types of torque wrenches: click-type, beam, slip, micrometer, and digital. On click-type, beam, and digital torque wrenches, a small scale indicates the amount of torque applied, expressed as newton-meters, foot-pounds, inch-pounds, kilogram force meters, and/or kilogram-force per square centimeter.
Q: What happens if a nut or bolt is over-torqued?
If a nut or bolt becomes over-torqued, it can easily break. Applying a torque level above the manufacturer's recommendation is rarely a cause for concern. However, we recommend erring on the safe side, as a broken nut or bolt could fall under sensitive parts such as your engine bay and be hard to retrieve.
Q: Do I really need a torque wrench?
Torque wrenches are absolutely essential if you plan on working on your engine or other powertrain components. These systems carry nuts and bolts of all shapes and sizes, such as cylinder-head bolts and exhaust manifold bolts that need to be tightened according to specs. Any over tightening could create stress on the system (e.g. distorted brake rotors) and cause parts to leak (e.g. coolant). Also, if a fastener is not tightened enough, it could become loose over time.
Q: Can you change a tire without a torque wrench?
Torque wrenches are not necessary for tire changes. Most cars come equipped with a spare jack and tire iron that are good enough to do the job by themselves. They are capable of fastening lug nuts anywhere from 80 to 100 pound-feet.
Q: How is torque calculated?
Torque is a measurement of rotational force that is expressed in foot-pounds. For example, applying 100 pounds of force using a 2-foot long wrench means you are applying 200 foot-pounds of force. Be sure to apply the correct amount of torque per manufacturers' specifications or run the risk of compressing, bending, or causing your fasteners to loosen prematurely.
