How to choose and how to use a torque wrench?

According to many novice drivers, the mostThe best tool for carrying out wheel replacement is the balonnik. But sometimes on the road happen really unpredictable things and if the motorist does not twist the nuts, they simply turn off and can crumble along the way. Then the wheel just fall off and the car will not go any further. And if this happened on the track at a speed of 100 kilometers per hour, the consequences can be unpredictable.

But strongly twisting the bolts is also dangerous,because then the thread on the wheel can break and the same thing will happen as in the case of undersized nuts. But how then to be? Luckily, in the auto shops there is a tool that allows the driver to tighten the bolts so that they hold tight and at the same time do not tear off the thread. Today, it's about how to use a torque wrench and how to choose it correctly.

Types of keys

Today in stores you can see three types oftools. These can be arrow, digital and snap variants. The answer to the question of how to use a dynamometric key, we'll find a little later, but for now let's consider each of the above-described types of parts.

The first type is the cheapest option, whichcan only be. But despite the low price, few of the motorists prefer this particular option. And the whole point is that the arrow dynamometric key (force) has a large error in the readings (9-10 percent). Therefore, its use in practice is comparable with the use of a conventional balonnik. Although the question of how to use the arrow-type torque wrench is set by a few motorists, since this spare part among all the existing options is the easiest to operate.

Snap variants have a smaller error,rather than the first type. It is about 4 percent. You can buy a snap-type torque wrench in any specialized store, but its value will be slightly higher (the so-called "golden mean"). It is also worth noting that snap options may be suitable not only for the usual motorist, as using a dynamometric key of this type is not disdained by the employees of major service centers, and there is nothing wrong with that. Universality is another trump card of this device.

The most expensive and, accordingly, the most accuratethe keys are digital. Because of their high cost, they are not at all suitable for the average car owner, and an additional set of functions is unlikely to help better tighten the bolt on the wheel.

Proceeding from this, it can be concluded thatThe best key for the Russian driver is a snap. Due to the low error rate it is excellent for both ordinary motorists and owners of service stations. Ease of operation and high degree of reliability make this type of spare parts one of the most popular in the world today. And it's very easy to use - you just need to adjust the scale, after loosening the "stop nut", and gradually rotate the handle until the device shows the maximum permissible rate.
