What is a Power Torque Wrench?
A power torque wrench is a useful tool for applying only a specific amount of torque to a fastening element such as a bolt, nut, or lag lock. It usually takes the shape of an open-end wrench with internal mechanisms.
It has an adjusting device that can sense the torque applied and then provide the appropriate change in tension, either clockwise or counterclockwise, depending upon what the situation is.
The tightening torque is frequently different from the loosening torque.
Why a High Impact Wrench (Power Torque) may be necessary?
It’s critical that nuts and bolts on an automobile be tightened to a Goldilocks-like “just right” degree. You risk losing a wheel while driving if the wheel lug nuts are too slack. You may not be able to remove them to repair a flat tire if they’re too tight. Bolts on engine heads and rubber suspension bushings are also important.
When you tighten a nut or bolt to a given torque, a torque wrench provides tactile, visual, or audible feedback to let you know when you’ve achieved the desired setting. Because most torque wrenches have ratchet handles with sockets attached, they come in four conventional socket drive sizes.
The longer the handle and the larger the drive, like with any other ratchet wrench, the more torque it can produce. For lug nuts and most other automotive applications, a 1/2-inch drive click-style torque wrench is appropriate.

Buying Guide
TORQUE RANGE AND SIZES
Automotive nuts and bolts come in a variety of sizes and forms. Each of them requires a certain torque range, measured in pound-feet or inch-pounds.
1/4-inch drive, 3/8-inch drive, 1/2-inch drive, and 3/4-inch drive torque wrenches are the four sizes available. The amount of torque exerted increases as the size increases.
With a maximum torque range of 50 to 250 inch-pounds, the 1/4-inch drive torque wrenches function with small nuts and bolts. The 3/8-inch drive ones operate with the most common nut and bolt sizes found in repair shops across the world, and they have a torque range of 15 to 75-foot pounds. Torque wrenches with 1/2-inch and 3/4-inch drive are used for bigger internal components with a range of 30 foot-pounds or higher, such as engine mounts, transmission mounts, and center-lug wheels.
ACCURACY
As a general guideline, go for torque wrenches that have been certified to have a 5 percent or superior accuracy. Look for an ISO 6789 accuracy certification to receive additional points. This certification ensures an accuracy rating of plus or minus 4% for up to 25,000 cycles. Even the tiniest departure from the proper torque might cause engine components to fail.
Please keep in mind that if your torque wrench is dropped or has been subjected to a lot of wear and tear, its accuracy may differ. As a consequence, it’s essential to calibrate and store it correctly from time to time to maintain accuracy. There are several sites online that detail how to calibrate a torque wrench step by step.
RANGE
Look for a torque wrench with a range of at least 150 foot-pounds, which is enough for tightening automobile lug nuts. Some can even exert 500 foot-pounds of force, which is required for more demanding applications. The light task requires less than 100 foot-pounds (e.g. bicycles and scooters)
ADDITIONAL FEATURES AND COMFORT
Under hoods or in dark regions, applying a lot of pressure puts an emphasis on ergonomics. Wrist or joint discomfort might develop if a torque wrench isn’t designed for comfort. Rubberized, knurled grips or steel handles with a raised grip are common on torque wrenches today. Some have adjustable heads (up to 15 degrees), allowing them to fit into tight spaces.
Visibility is a focus of other auxiliary characteristics. Many torque wrenches include LED lights that turn a certain color when the appropriate torque is met. Some even make noises that are alarming.
Keep readability in mind. The scales must be simple to read. To determine the present torque level, a single look should be enough. Torque is indicated by scales located on the handle of click-type torque and beam wrenches. The most basic of all the digital torque wrenches use a digital scale. Scales are only used with slip-style torque wrenches.
STORAGE
When it comes to your torque wrench, don’t skimp on a suitable carrying case. Your tool kit’s sensitivity and accuracy may deteriorate with time as a result of continuous wear and tear or bumping. Look for torque wrenches that come with a well-padded storage case.
Other Things to Think About
Accuracy. A torque wrench must be as exact as possible in order to get the greatest results. The calibration and precision of the device itself have a role in inaccuracy. On a beam torque wrench, for example, the beam must be positioned appropriately. The readout of the wrench also affects accuracy.
Because of the digital display and/or sound indication, electronic and click-type wrenches often provide better results.
Comfort. Because all torque wrenches need the user to exert force in order to operate, overall ergonomics must take comfort and usefulness into account. The overall comfort of the wrench is influenced by the size, length, and grip of the shaft, for example.
It’s simpler to apply more torque with less effort when you have more leverage. Even if your hands are slick from engine oil or automotive grease, a grip makes it simpler to keep a tight grasp on the wrench.
Ratchet Design. A ratcheting head is a simple approach to keep a consistent degree of torque while the total quantity is increased. For example, beam torque wrenches require you to apply the torque in a single spin. Ratchet wrenches, on the other hand, maintain the current torque level when you spin the handle to apply extra force.
Electronic and click-type torque wrenches often use a ratchet. Steel structure, a reversible ratchet mechanism, fast release buttons, and a beautiful chrome finish are all superb design features.
Let us see some frequent asked questions (FAQs) about a Torque Wrench
- WHAT IS A TORQUE WRENCH, EXACTLY?
A torque wrench is used to tighten a nut or bolt to a certain torque level as specified by the manufacturer. Torque wrenches are divided into five categories: click-type, beam, slip, micrometer, and digital.
A tiny scale on click-type, beam, and digital torque wrenches shows the amount of torque exerted in newton meters, foot-pounds, inch-pounds, kilogram-force meters, and/or kilogram-force per square centimetre.
- WHAT HAPPENS IF YOU OVER-TORQUE A NUT OR BOLT?
A nut or bolt may easily shatter if it is over-torqued. Torque levels that are higher than the manufacturer’s recommendations are seldom a reason for worry.
However, we advocate erring on the side of caution since a broken nut or bolt might fall into sensitive sections like your engine compartment and be difficult to recover.
- DO I ACTUALLY REQUIRE A TORQUE WRENCH?
If you’re going to work on your engine or other power-train components, you’ll need torque wrenches. These systems include a variety of nuts and bolts, including cylinder-head bolts and exhaust manifold bolts, that must be tightened to specifications.
Any excessive tightening might put the system under stress (for example, deformed brake rotors) and cause components to leak (e.g. coolant). In addition, if a fastener is not properly fastened, it may grow loose over time.
- CAN A TIRE BE CHANGED WITHOUT A TORQUE WRENCH?
Tire changes do not need the use of torque wrenches. Most automobiles come with a spare jack and tire iron that are capable of doing the task on their own. They can tighten lug nuts with a force of 80 to 100 pound-feet.
- HOW DO YOU DETERMINE TORQUE?
Torque is a unit of measurement for rotating force, and it is measured in foot-pounds. Applying 100 pounds of force with a 2-foot long wrench, for example, equals 200 foot-pounds of force. If you don’t apply the necessary amount of torque according to the manufacturer’s instructions, you risk compressing, bending, or loosening your fasteners prematurely.
