The Buyer’s Guide
A torque wrench tool is a precise and small instrument with a torque measurement mechanism. Using such a tool, you will be able to tighten the fasteners to the required torque.
Most often, a tool with a built-in torque is used for repair and maintenance of automobiles, commercial vehicles, industrial equipment, construction equipment and assembling high-tech mechanisms. In all these cases, too much or too loose fasteners are at risk of breaking or loosening and falling out, which can lead to significant damage to vehicles.
As you’ve probably noticed, there are a few different types of torque wrenches for cars:
- Beam torque wrenches – the information about the applied force (torque) is transmitted on the scale that looks like a beam. This is the most affordable, least accurate and, frankly speaking, the most inconvenient wrench to use. It is worthy of your investment only if you do occasional and simple car repair jobs – for instance, if you need to tighten the engine’s screws once or twice a month;
- Drive-click torque wrenches – such instruments are much more accurate and convenient than beam tools, and at the same time, the price of click wrenches is significantly lower than digital instruments. That is why click torque wrenches are the most popular choice among professional mechanics and regular car owners;
- Digital/electronic torque wrenches – these accurate instruments inform the user with a loud beeping signal, light indicators and numbers on a LCD screen. These are the most expensive and most accurate wrenches in the market right now. There is no need to buy them if you have a single car and tighten the screws occasionally. These tools are mostly recommended for heavy-duty tasks in car repair shops. If you want to keep the expensive car engine safe, choose a digital automotive wrench;
The most important things to check before buying
- The maximum and minimum torque range;
- The size of the drive (squared connection);
- Correspondence to the ISO 6789 standard;
- Comfortable handle grip;
- A storage case should be sturdy;
- The overall length of the tool;
The most important factor is a torque range of a certain tool. Pick the wrench according to this setting.
For instance, you need to tighten the engine screws and the manual says that you should tighten these nuts with the maximum applied force of 110 Nm. It means you should pick the torque wrench the range of which is at least twice higher than 110 Nm.
Every manufacturer typically specifies the torque range for their instruments. In this case, you should buy the tool with the torque range from 40 to 220 Nm. The drive should be no less than 1/2 inches.
How to calibrate an automotive torque wrench at home?
- DIY calibration of a torque wrench requires from you setting the exact moment of the applied force (torque). At home, you can use a cantor or any load with the exact weight marking (dumbbells);
- Install the tool’s handle at the position and angle;
- Check if the wrench works;
- If a click occurs before the load moves, then you need to decrease the calibration of this instrument;
- If the weight rises without a click, the calibration should be expanded;
- Adjustment of the torque wrench is made until the load barely rises along with the tool’s click or beeping;
- When the required parameter is set, the lock knob must be tightened;
- The lock nut is installed and tightened to lock the calibration mechanism;
How to use an automotive torque wrench?
- Check the fastener type before picking a torque wrench. Typically the car manual or online forums can help to define the fastener’s size and type;
- Clean the fastener of dirt, grease and corrosion spots;
- The bolts or screws should be not be crooked or damaged – you may break the tool if you tighten one of such damaged fasteners;
- It is not necessary to lubricate the threads before applying the torque wrench. A lubricant may reduce friction and distort the results of tightening;
- The use of a torque wrench is usually recommended after pre-tightening of the fastener with a screwdriver;
- When tightening the fastener, check the visual readings only at right angles. Keep in mind that some torque wrenches have not very visible readings and you may need to use a flashlight or smartphone to read these markings correctly;
Picking the torque wrenches for automotive projects
The most common type of high-precision manual instrument for fasteners. Structurally, they resemble a ratchet for socket heads, in the drive of which a measuring mechanism is mounted.
Torque wrenches picked for automobiles are divided into 3 major types:

Torque Wrenches for Automotive FAQ
What is the best wrench for cars?
A torque wrench’s primary function is to tighten a bolt to a certain torque configuration. You obviously cannot do this with a standard wrench, and much of the time it is a game of chance that ends in the part being over- or under-torqued.
The torque wrench may be used for a variety of tasks other than locking the cartwheel bolts. It’s a ratchet with a stick, but it also has torque settings. The most popular use, though, is for tightening cartwheel bolts.
There are many premium torque wrenches for automotive purposes. For example, you may pay attention to these tools:
- Gearwrench 85078 flex head electronic wrench;
- Tekton 24335 ½-inch drive click wrench;
- Amazonbasics 1/2-inch drive click wrench;
- Epauto 1/2 inch drive click wrench;
- eTork click-style 1/2-inch drive wrench;
- Lexivon LX-181 1/4 inch drive wrench;
Who makes the best quality torque wrench?
A ratchet system is used in modern torque wrenches. It enables the customer to hold the wrench on the fastener even though it has reached the end of its journey in the work area. Turning the wrench in the opposite direction of its planned movement is all that is needed. The gear within the wrench head is used by the ratcheting mechanism to enable the handle to slide backward whilst the fastener stays stationary. It allows smoother processing in a confined room.
The most recognized manufacturers for automotive-ready torque wrenches are:
- Snap On;
The operating philosophy is the same with all brands, although the accuracy, reliability, and prices vary. They are offered in a variety of sizes and lengths and can be purchased in department stores as well as online retailers such as Amazon. Until choosing or purchasing a torque wrench, you should first recognize its characteristics and then choose the right tool for your needs.
What is the torque wrench range for cars?
There are a few categories of automotive torque wrenches if you seek the tool with a different torque range:
- The size of very light-duty instruments is 15 to 75 foot-pounds. This category includes typical repair items including spark plugs, valve cover bolts, oil drain plugs, and other related fasteners;
- Light-duty tools have a torque scale of 30 to 150 foot-pounds. The majority of car fixes fall under this category. In other terms, you won’t be able to finish the bulk of car fixes unless you have a torque wrench in this range. Head bolts, caliper bolts and lug nuts are common maintenance needs in this range;
- Medium-duty tools have a torque capacity of 50 to 250 foot-pounds. While this category contains fewer fasteners than light-duty fasteners, those that do are used in sensitive applications. Axle bolts, hub bolts, and bolts on mounted vehicle hitches are some of the most popular automobile fastening applications within this torque range;
- Heavy-duty tools have torque ratings ranging from 120 to 600 foot-pounds. Driveline modules and bearings, as well as most of the work used in transfer cases and differentials, are popular applications;
The wrench you need would be determined by the sort of automotive work you do. If you’re only concerned with oil adjustments and tune-ups, you’ll probably just need light or rather light-duty wrenches. You’ll need a heavy wrench if you are a car mechanic specializing in hard duty maintenance, such as repairing engines/transmissions or handling structural repairs including axle or hub service.
What is the proper size of torque wrenches?
There is no such thing as “the best torque wrench size” because each torque tool size is required for various user cases. The most common size of torque wrenches for automotive bolts, nuts and fasteners is a 1/2-inch drive socket.
It is the drive’s default size. It is suitable for lug nut installation and operating on car suspension. If you don’t even have a wrench, you’re usually removing lug nuts on your car with a lug wrench or tire iron.
A 1/2 inch wrench usually has a working length of 30 to 160 ft. lbs. It is the proper tool size for lug nuts and other hard fasteners.
What is a decent cheap torque wrench?
It is better NOT to save money on such an essential instrument as a torque wrench. Because cheap torque wrenches are usually not quite accurate and may lead to serious damages to your car’s fasteners.
However, some reputable brands produced a few affordable torque wrenches with premium quality. For instance, you may try such budget-friendly tools from premium wrench manufacturers:
- Tekton 1/2-inch click wrench;
- eTork click-style wrench with pre-set values;
- Performance Tool W3001C ½-inch beam wrench;
- EPAuto 1/4-inch click wrench;
- Neiko 03727A ¼-inch beam wrench;
If more people understand how useful this method is, more producers are producing torque wrenches. The price of a torque wrench is heavily influenced by the materials used, the manufacturing process, and the brand’s reputation.
A basic torque wrench can cost between $150 and $300. Other reasons, such as the product’s demand at the moment, or additional services such as one-day delivery that cause prices to rise slightly.
There are several choices available, ranging from $50 to $1000, so you can quickly find one that suits your budget.
Is it possible to apply a foot-pound wrench for inch-pounds?
You’ll need a torque wrench, which detects smaller values of torque in foot-pounds and converts them to inch-pounds.
Since the inch-pound wrench doesn’t measure in foot-pounds, a quick conversion is needed. Since 1 foot equals 12 inches, e.g. 20 multiplied by 12 equals 240. Or you may use an online calculator and converter to figure out how to use a foot-pound wrench with inch-pound measurements.
Are automotive digital wrenches more precise than other wrenches?
The key benefits of digital wrenches are precision and ease. Digital wrenches are very precise devices. Their more fragile construction, on the other hand, necessitates extra caution while treating. It necessitates maintenance and calibration, as well as precise storage specifications. Though, beam-style wrenches are typically considered more accurate than any other tools for tightening bolts and lugs.
