Besides an efficient and versatile torque wrench, you may also need a torque angle gauge to check that all fastener components have the same amount of tightness. A wrench may not detect the improper tightness numbers on the bolt surface, especially if the bolt is too small or massive.
However, the small tools called torque angle gauges can measure how much force is required to turn the fastener without deformation or breaking a more expensive torque wrench. This tool is essential for measuring torque of bolts, screws, cylinders and fasteners of all kinds. Mostly, these gauges are necessary if you prefer repairing your car on your own.
What is a torque angle method?
To figure out the tension necessary to apply to a bolt before fastening, a torque angle gauge is used. The method of electronic measurement of the bolt is called a torque angle method (a.k.a. snug torque method). Take it as a final accuracy check before applying torque force and proper angle rotation. With such a small tool, you will find out how to fasten the bolt equally at different angles. In such a way, you specify an angle of fastener’s turn before actually rotating it.

The Buyer’s Guide
Experts and professional car mechanics recommend investing only in metal angle gauges because this material can significantly improve their use. Plastic models are typically cheaper but their quality is far from superiority. To make these tools even more durable consider using roll-up pouches.
One of the major reasons to buy a high-end torque angle gauge is to learn the proper measurements of different bolts and nuts before applying a wrench. Accuracy is a must-have feature when you pick the gauge of this type. Proper accuracy will deliver flawless results and protect you from breaking important vehicle parts.
An angle gauge must be easy to read even in the dark. Otherwise, you won’t be able to measure the torque range of a fastener properly. Consider sticking to digital angle gauges with small LED screens or, at least, invest in the tools with engraved markings or large scales.
Other tips for buyers of torque angle gauges
- Digital readers can work from all angles – they are quite flexible;
- You should not buy a torque angle gauge to replace just an angled gauge. They share similar uses but an angled gauge works less accurately, though, much faster. With a torque angle gauge it is possible to measure the angle while working;
- It is not necessary to place the gauge to the ratchet head to measure the angle properly;
- Not all gauges reviewed here can be used for all vehicles. They are not universal tools. Make sure you buy a torque angle gauge compatible with your car or motorcycle;
Torque Angle Gauges FAQ
When is the torque angle gauge used?
When servicing several late-model engines that apply torque-to-yield fasteners, drive torque angle gauges are needed.
Torque angle gauges are a comparatively modern way of tightening fasteners in motors. The aim is to achieve a more reliable stretch in the bolts. Since a wrench detects pressure, several factors may influence proper tightening.
To begin, use the torque wrench to apply a small amount of initial torque to the bolt to seat it. After that, rotate the bolt a certain amount of times. Now, the maker may be very certain that the right stretch is being applied to the bolt.
What is a Torque Plus Angle specification?
A fastener with a Torque Plus Angle (TA) spec should be tightened first to the torque part of the feature, followed by the addition of the specified angle. The angle has to be applied with the compatible fastener, whether one is present, or to the compatible board. If necessary, a contingency wrench must be used to keep the mating fastener from rotating when the angle is applied to the fastener with the TA feature.
A Torque Plus Angle-to-Yield (TAY) approach is also available. A fastener with a TAY spec is adjusted in the same manner as a fastener with a TA specification is tightened. The distinction between a TA and a TAY definition is that tightening causes irreversible deformation of the externally threaded fastener.
When a TA or TAY tightening feature is measured, a smaller fastener may be used for the additional advantage of improved clamping power. An M12 bolt with a TAY specification, for example, should be used in lieu of an M16 bolt with a Torque (T) feature. The usage of TA and TAY requirements reduces vehicle weight and, as a result, improves fuel efficiency.
Why is torque angle important?
Torque is the quantity of energy added to a bolt/nut. Angle is the degree of angular movement of a bolt/nut.
Torque coupled with angle tightening approaches will minimize tightening process instability by minimizing dependency on torque control alone. On a given bolt, the nut progresses down the thread by a set amount of millimeters on any 360-degree revolution of the bolt. This is known as the thread pitch.
A torque angle measurement is an exact final examination for the force added to a bolt when toughened. An angular torque wrench calculates both torque force and angle movement electronically.
Does the angle affect torque?
What is the purpose of a fastener? A bolt is applied to hold two items. In vehicle applications, there are always guidelines about how closely the two individual pieces can be held together. If the fastener is too close, you risk damaging the components or the fastener itself. Very loose, because there isn’t enough clamp load, and the two pieces will leak or move under load.
The sum of clamp load (how hard the fastener “squeezes” the two things it’s joining) is calculated by the fastener’s diameter, content, and stretching. You should find some way to calculate bolt stretch so we can’t measure the real stretch of a bolt (except for rod bolts).
For several years, the car industry relied on torque values as a yardstick. The idea process was that by measuring the sum of rotational resistance, one could calculate how much force was being applied on the threads. Although this is still a highly useful way of assessing clamp load, it has several disadvantages and inconsistencies.
How do you read torque specs?
There are 3 ways how you can read the specs of torque wrenches. It depends on the torque wrench type:
1) How to read a micrometer wrench:
- Turn the knob on the handle’s end counter-clockwise;
- Look for the numbers mentioned vertically above the handle. On both sides of your wrench, you can see two sets of vertical numbers. The numbers on one side of the wrench will be in foot-pounds, or ft.-lbs., while the numbers on the other side will be in Newton-meters, or Nm;
- Locate the numbers that are wound around the wrench’s shaft;
- Turn the wrench handle to change the torque setting. Converting the handle clockwise increases torque, thus turning it counterclockwise decreases it;
- Adjust the wrench to achieve the desired torque. To achieve the desired setting, align the vertical line on the handle with the vertical line above each amount on the micrometer;
- Adjust the knob at the wrench’s edge. Turn the knob at the wrench handle’s edge clockwise. This tightens the wrench and sets the torque frequency on the wrench;
- When working, have an ear out for the click;
2) How to read the specs on a dial/beam-style wrench:
- Examine the meter at the wrench’s base. At the bottom of the wrench, there should be a meter with numbers and an arrow. The figures indicate the sum of torque in foot-pounds (ft.-lbs.) or Newton-meters (Nm). The sum of torque applied to a lug/nut is shown by the position of the arrow. The wrench can read 0 while in the stationary position;
- Place the tool around a nut/bolt and examine the arrow. The arrow can rotate when you spin the instrument around a nut/bolt, representing the amount of torque you’re adding.
- A memory arrow can be found on certain dial torque wrenches;
- Tape a sheet of tape to the preferred torque line to make it easier to learn. Without the tape, it can be difficult to see the lines and numbers on a beam or dial-style wrench;
3) How to read a digital wrench:
- Go through the user manual that arrived with the wrench. The torque levels on your wrench may be adjusted according to the instructions in the manual. Remove some lubricant or tape from the threads of the bolt you intend to torque. Other parameters on certain digital torque wrenches influence the sounds and vibration speeds;
- Using the arrow keys, set the desired amount of torque. To adjust the torque setting on the wrench, press the up or down arrow. Continue to tweak the numbers before you reach the optimal amount of torque;
- Use the percent (%) key to set the tolerance parameters;
- If the wrench lights up or creates a racket, stop spinning it. When you hit the necessary torque, the wrench can create noise, light up, or vibrate. When this occurs, stop spinning the nut;
For instance, if you adjust the tolerance specifications to 10%, the wrench would begin to light up and vibrate when you’re within 10% of the target torque. Set the tolerance specifications by pressing the percent key and then adjusting the percentage with the arrow keys.
Video Tutorial: Torque Angle Gauge Overview & Review
Before buying a torque angle gauge, consider checking the specs carefully. The instrument should be fully compatible with your vehicle type. The torque range and drive size must be compatible with the gauge’s specs either. Durable metal gauges may last longer than cheaper plastic alternatives. And, do not forget that this instrument is only an accessory to a full-fledged torque wrench.
