What Is a Torque Wrench?

A torque wrench is a tool used to tighten fasteners such as bolts and nuts to a precise torque value. The tool is an important element in mechanical operations. You will find torque wrenches in a wide range of industries, but it is most commonly used by auto mechanics.
A torque wrench allows mechanics to fasten a bolt or nut to the manufacturer-specified tension level. This prevents applying excessive force during fastening operations, reducing the chances of damaging fasteners and joints.

Manufacturers go through a lot of trouble to calculate the torque specifications for every component in their products. The preset torque is not merely a design parameter; it is vital for the optimal performance of a product and the safety of the user.

Take, for instance, over-tensioning a fastener after a tire changing operation. Excessive torque can damage the wheel joint, weaken the fastener, and jeopardize the safety of the car occupants. This is why torque wrenches are so important.

It is important that you don’t confuse a torque wrench with an impact wrench. An impact wrench is designed for heavy applications, while the torque wrench is a precision tool.
You use the impact wrench for the loosening and tightening fasteners quickly. However, a torque wrench is designed for precision measurement jobs. It is extremely sensitive to pressure and not ideal for undoing bolts and nuts.

    You want to choose a torque wrench that can provide reliable and consistent accuracy over a wide range of applications. Thankfully, you can get very precise torque wrenches that have a high level of consistency at affordable prices. Whatever you do, make sure the product you buy can deliver the accuracy you need for your fastening applications.

  2. Load Limit

    Another vital consideration when buying a torque wrench is the load limit. This factor determines the type of fastening applications you can do with the instrument. So it is essential to check it before picking a model.
    The load limit is the amount of pressure you need to exert on a fastener to reach a specific torque. It depends on the size, weight, durability of the tool.
    Buy a large wrench if your fastening projects require a high amount of load limit. If you bought a small-sized torque wrench, you may not get the desired results.
    The rule of thumb is to buy a tool with a higher load limit than the work you intend to do. That way, you can easily complete torqueing jobs without the risk of damaging your precision tool or fastener.

  3. Size

    torque wrench sizesThere are four different sizes of torque wrenches. The 1/4″ drive is ideal for small fasteners and can produce up to 21 foot-pounds of torque. You can use the 3/8″ drive to deliver up to 15 to 75 foot-pounds of torque. The 1/2″ drive is suitable for larger fasteners used to mount suspensions and engines. Large rigs and aircraft and marine engineers use the 3/4″ drive.

  4. Weight

    The weight of a torque wrench plays an important role in the type of work you can use it for. If you work in tight areas, such as underneath a car, consider buying a lightweight model with adjustable length.
    The size also determines the load limit. Obviously, a light torque wrench will have a lower load limit compared to a heavy-duty model. Consider how the size of the tool will after ease of use, your workspace, and the work you do.

  5. Material

    The material used to make a torque wrench is important for its longevity and durability. It can also determine the value you will get from your purchase.
    There are models that have all-steel construction, while others are made from alloys such as chrome vanadium. Some manufacturers use a mix of metal and plastic or other synthetic materials.
    The most durable torque wrenches on the market are the all-steel and alloy models. They may have a plastic or rubberized grip, but the whole wrench is sturdy and durable enough to last for many years.
    A good way to identify long-lasting products is to read customer reviews. Lengthy warranty periods can also help you identify manufacturers who have confidence in their product.

  6. Consistency and Reliability

    Manufacturers can claim calibrating their torque wrench to an accuracy of less than 2%. But can the tool provide reliable torque measurements consistently after a long period?
    It’s difficult to determine which brand offers consistent and reliable performance except you’ve used it for some time. The best way to find this information is to read honest customer reviews.

  7. Design

    digital vs manual torque wrenchThe two main types of torque wrenches are the manual and digital designs. If you work in confined spaces, a torque bar with a long handle will make access easier. Some models are designed for repetitive tasks, so you don’t have to stop working to readjust it frequently.
    Besides the beautiful digital display and flashy grips, you want a tool that is accurate and reliable. It should be easy to use, sturdy, and built to last. The most important thing is to buy a product that suits your fastening projects.

  8. Scale Readability

    The top torque wrench brands use scales readable in low light conditions. It should also come with dual-range scales. This means it has scale settings for imperial and metric measurements.
    Most of the world use the metric scale, but some companies in the US stick to the imperial system. Thankfully, dual-range scales allow you to work with different fasteners without complicated conversions.

  9. Ergonomics

    Buy a torque wrench with improved ergonomics. The product should have the ideal length, weight, size, and design.
    Models that have large handgrips make it easier to work in comfort for longer with oily and slippery hands. A torque wrench that can ratchet will also make your work faster and less physically demanding.

  10. Affordability

    The cost of a torque wrench depends on several factors, including the material, design, features, and load limit. If your work doesn’t require high levels of accuracy, go for models with standard features. It is better to invest in the most feature-rich torque wrench if you perform precision fastening jobs.

6 Important Features & Specifications of Torque Wrenches

Types of Torque Wrenches

There are different types of torque wrenches. Each type has a unique design and features and serves specific fastening applications.

Here are Some Common Torque Wrench Types & Their Uses

  1. Beam Torque Wrench

    Beam-style torque wrenches have a square head that comes with a pointer beam on a scale. As you twist the wrench, the beam remains in place while the scale shows the amount of torque being applied. Once you reach the preset torque limit, the scale stops at that number.
    Beam-style torque wrenches are easy to use and very affordable.

  2. Click-Style Torque Wrench

    This style of wrench is so-called because it makes an audible click when you reach the torque limit. The tool comes with a spring-loaded lever that you adjust by twisting the handle.
    The lever breaks when you reach the set torque level, creating a clicking sound. Most click-style wrenches can ratchet, so you can use them in clockwise and anticlockwise direction.

  3. Electronic Torque Wrenches

    Electronic or digital torque wrenches feature a sensor which detects the amount of force you apply to a fastener. A circuit converts the force into electrical current and shows it on a digital display.
    Digital torque wrenches are common in auto mechanic workshops. They have a memory stick for recording a wide range of torque settings for different fasteners. These models are especially useful for angle tightening.
    Depending on the model, they can give beep, lighting, or vibration signals after reaching the torque level. With digital torque wrenches, you can perform several fastening applications without manually setting the torque.

  4. Dial Torque Wrenches

    Dial torque wrenches have a wider design than other models. They have a wrench head, a handle, and a dial scale in the middle to show the level of torque.
    Dial torque wrenches are used for applications that require extreme precision. They are common in the aeronautics, defense, and manufacturing industries.

Differences Between Wrench Types

  • Torque Wrench Vs Socket Wrench

    A torque wrench is a precision tool that lets you monitor the amount of pressure to apply to a fastener. In most cases, you shouldn’t loosen a fastener with a torque wrench; it is designed mainly for tightening bolts and nuts to a manufacturer specification.

    The socket wrench or ratchet and socket combination is a tool that comes with detachable sockets. The ratchet is a wrench which you insert into the socket to either loosen or tighten a faster.

    The main feature of the socket wrench is that you can pivot the tool back and forth without removing the socket to reposition it.
    The torque wrench and ratchet wrench both have a socket attached at one end. The only difference is that the latter helps to tighten or loosen fasteners while the former guides you to a precise tightening to meet specific torque settings.

    Both the torque wrench and socket wrench work together. But there are torque wrenches that have a ratcheting head, allowing them to tighten and loosen bolts and nuts.

    Meanwhile, here is a comprehensive guide if you are looking to buy the best jump starters on the market.

  • Impact Wrenches Vs Torque Wrenches

    The impact wrench and torque wrench are both used for fastening operations. But they are two different tools with specific uses and features.

    A torque wrench is a precision hand tool that allows you to tighten bolts and nuts accurately. An impact wrench is a power tool that uses immense force to loosen or tighten fasteners, but with limited accuracy.

    While the torque wrench is manual, the impact wrench is powered by air, battery, or electric. Because it is a power tool, you can use an impact wrench for long hours without fatigue.

    A torque wrench is hand-operated and will cause excessive discomfort after a few hours of use. To avoid fatigue, use the impact wrench for the heavy fastening and finish the job with the torque wrench.

    Torque wrenches are silent, but impact wrenches may require the use of ear protection because they make a lot of noise. An impact wrench is also relatively more expensive compared to a torque wrench. However, some hydraulic torque wrenches can be very expensive but are only used for specialist jobs.

4 Benefits of Using a Torque Wrench

The torque wrench is very important in repair and maintenance work, especially in the automotive workshop. Auto mechanics use it to achieve precise torque levels while tightening different types of fasteners. The following are some benefits of using a torque wrench:

  • Improves Accuracy
    The biggest advantage of using a torque wrench is that it allows you to tighten fasteners to a specific accuracy. This is especially important when you are performing jobs like changing tires or installing engine parts.
    While some fastening operations require brute force, others need to be precise. A torque wrench allows you to complete your fastening projects correctly without wasting time or damaging the joints and fasteners.
  • Ease of Use
    Another big benefit of the torque wrench is simplicity. The tool does not need power or any specialized training. All you need do is learn the correct way to set and adjust the torque and how to maintain it.
    By design, torque wrenches also prevent application of excessive force. You only need to exert the amount of pressure to reach a specific torque level.
  • Reduces the Risk of Accidents
    Torque wrenches are so important because they can help prevent accidents and save lives. The tool allows mechanics and other auto technicians to achieve the correct manufacturer specified tightening during repair and maintenance operations. This means you can prevent over and under tightening bolts and nuts and reduce the risk of failures.
  • Less Maintenance
    Over tightening or under-tightening fasteners can increase wear and tear, which increases the cost of maintenance. Poorly tightened fasteners can also lead to costly damages, many of which will cost thousands of dollars to replace or repair. The correct use of a torque wrench can help you achieve precise fastening specifications and prevent costly maintenance.

How Does a Torque Wrench Work?

how does a torque wrench work diagramTo understand how the torque wrench works, it is important to know the meaning of torque. Torque is the force exerted by rotational force. For torque wrenches, the foot/pound measurement indicates the amount of force (in pounds) applied for every foot rotation of the wrench head. So what the torque wrench does it help you apply a specific rotational force per foot to a fastener.

Take, for instance, a nut that is rated 200 pounds-feet of torque, and the wrench is 2 feet long. You will need to turn the wrench several times until you have applied 200 pounds of force.

Torque helps to balance the clamping force between a joint and fastener. If it’s excessive, you risk wearing the joint and the fastener or even causing more extensive damage. Too weak, and the fastener might come loose spontaneously.

A torque wrench works by applying a specific amount of force per feet on a fastener. The goal of the torque wrench is to prevent you from overloading a fastener and the joint that supports it.

Presicion Measuring With a Torque Wrench

Because a torque wrench is a precision instrument, you need to handle it with care. You also need to know the correct way of setting and adjusting the torque to get the best results.

Most manufacturers precalibrate their torque wrenches to an accuracy up to +/- 3-4%. This allows you to use the tool for precision fastening jobs for a long time without recalibration.

But the factory calibration is not enough. You won’t get precise and consistent results if you don’t know how to set the tension and use the tool.

In subsequent sections, we discuss the important specifications and features to look for in torque wrenches. You will also learn the proper way of using a torque wrench and more.

How to use a Torque Wrench in 5 Steps

Here is how to use a torque wrench correctly:

  1. Check Torque Specifications
    The first step is to check the torque specifications for the bolts or nuts you want to tighten. Don’t guess if you don’t know to avoid problems.
    Most shops and service manuals have the torque values for fasteners, but you can check it online, too. Make sure you are using the most recent torque specifications because manufacturers can change them at short notice.
    Also, don’t lubricate fasteners except the manufacturer tells you to do so. Otherwise, you will reduce friction between the fastener and the joint, causing dangerous overloading.
  2. Adjust the Torque Wrench
    Before you adjust the torque wrench after a long period, reuse it for several times to make sure the internal parts are free. Then unlock the adjuster if you are using the click-type or beam-style torque wrench. Remember to check whether the fastener is calibrated in foot-pound or inch-pounds and set the torque value accordingly. After setting the torque value, lock it in place.
  3. Tighten the Fastener
    The next step is to tighten the bolt or nut as required until you reach the torque value. You can use an impact wrench to start the work and complete the last tightening with a torque wrench. If your torque wrench has a ratcheting mechanism, it can help reduce the time and effort, too.
  4. Get the Precise Torque
    When the fastener becomes tight, use the torque wrench to apply steady, even pressure until you hear an audible click. The tool may also alert you with a beep and other signals, depending on the design.
    While tightening the fastener with the torque wrench, keep the handle centered on its pivot. Otherwise, the tool might lose its accuracy.
    Also, some fastening jobs, such as those of engines and suspensions require torqueing plus angle. This requires tightening each fastener snugly one after the other before torqueing in sequence. The method aims to compensate for disparity in fastener quality, friction, load, tension, and other variables.
  5. Remove the Torque Wrench
    Once you have tightened the fastener to the correct torque, remove the tool and store away. If the torque wrench is spring-loaded, set it back to a minimum value to prevent tension loss.
    Meanwhile, here is a detailed tire inflator buying guide so you don’t get stranded by flat wheels.

How to Calibrate a Torque Wrench?

Torque wrenches are precision measurement tools you need to handle with care. They also require regular calibration to provide accurate and reliable results consistently. It is necessary to know how to calibrate your torque wrench periodically to get the best out of the tool.

That said, the best way to calibrate your torque wrench is to hire a professional to do it. But there is no harm in knowing how to recalibrate the instrument yourself, even if the process may not be perfect. Below, we discuss how to calibrate a click-style torque wrench.

Get Supplies

First, you need to get all the supplies to perform the calibration. These include:

  1. Tape measure
  2. Click-style torque wrench
  3. Marker or paint pen
  4. 20-35-pound weight
  5. A means of restraining the torque wrench, such as a bench-mounted vice or lug nut
  6. String or rope that can support the weight
  7. Pen and paper to record your calculations

Calibrating a Torque Wrench Step by Step

  • Step 1. Measure Your Torque Wrench

    Capture your measurement from the center of the square drive and stop at the handle. Remember to mark where you stop. For example, if you have a 20″ torque wrench, start measuring from the point where you attach the socket wrench and stop at the point where you hold the handle. This should be around 18.” Note the value on the paper.

  • Step 2. Restrain the Torque Wrench

    The next step is to secure your torque wrench. For more accurate results, lock the square head in a vise mounted on a table. Otherwise, secure a socket wrench on the square drive and place it on a lug nut fastened to sturdy equipment.
    Secure the torque wrench horizontally so you can suspend a weight on it vertically. The handle should move freely after securing the square head.

  • Step 3. Calculate Your Torque

    To calibrate the tool correctly, you need to calculate the torque. This requires multiplying the length you measured in step 1 by the weight you want to hang on the handle. Here, let’s say 20 pounds. You then divide the answer by 12 to get the foot-pounds. The answer will give you the torque value of the instrument.
    15 inches x 20 pounds = 300 inch-pounds
    300 inch-pounds/12 = 25 foot-pounds.

  • Step 4. Attach Weight to Calibrate the Torque Wrench

    Now that you have the torque value, secure the cable or rope to your weight. Then make a loop on the free end to suspend the weight on the tool. Set your torque wrench to 25 foot-pounds. Next, hang the weight on the point where you marked in step 1, suspending it in mid-air. If the torque wrench clicked, it means it is calibrated.
    To test the accuracy of the test, adjust the torque setting to 26 foot-pounds and listen. If you don’t hear a click, it means you have correctly calibrated the tool. If the torque wrench did not click when you suspended the weight, it is not calibrated, and you will have to adjust the setting manually.

  • Step 5. Adjust the Torque Wrench

    Remove the weight and adjust the spring tension in the tool with a screwdriver. There is a screw midway between the wrench handle and the square drive. Turn the screw clockwise gradually.
    Then hang the weight at the mark on the handle and listen for a click. Repeat this process until the tool clicks. Confirm the click by removing and replacing the weight and listening for the click.
