The torque wrench or torque wrench is a device used to tighten bolts or nuts with a level of strength and firmness that can be adjusted to the needs. From this definition we can conclude that the function of the torque is to measure the torsional force on nuts and bolts to reach a certain moment of tension.

To carry out its work, the torque key consists of two ends with different functions. One side of the tip of the torque wrench is used nut or bolt to be tightened, while the other end is used to see the level of strength or tightness of the nut or bolt tightened.

Considering the community's need for a variety of torque wrench, producers are competing to create several types of torque wrenches that can be tailored to their needs including the torque wrench deflecting beam model, torque wrench model dial indicator, torque wrench micrometer setting model and Click model (Click Adjustable).

Torque Wrench Deflecting Beam

The defecting beam Torque wrench is a type of torque wrench that will indicate the level or size of the tightness of the nut or bolt that is tightened from the pointer rod. This needle will move towards certain numbers or scales, where this movement is based on the magnitude of the tightening moment performed.

Key Torque model Dial Indicator

As the name implies, this type of torque lock uses an indicator dial as a strength gauge or the tightness of nuts and bolts. The Dial Indicator, also known as the dial gauge, can be used to check deviations with very small scales from the cylindrical plane, spherical plane, flat plane and alignment. The measurement itself depends on the type of dial indicator used but generally the level of accuracy can range from 0.01 mm to 0.001 mm.

Dial indicator itself is a measuring instrument that cannot stand alone so it must be attached to a tool. In the installation process this must be considered carefully, where the position of the dial gauge must be installed in a position parallel to / perpendicular to the measuring point. In the world of automotive, this one measuring instrument is one that is widely used.

Torque Wrench Model Setting Micrometer

This type of Torque wrench allows us to be able to adjust the moment of tightness of nuts and bolts as desired by adjusting the size of the tightness or setting the micrometer on the handle of the torque. With a certain size, the shock lock can tighten the nuts and bolts. And one of the producers for this type is Promax.

Thus information about the types of torque wrench or torque wrench, hopefully can be useful. In general, the Torque wrench is used for final hardening, after being hardened at the initial stage by using an ordinary key like a shock lock. In addition, this tool also functions to find out the moment of firmness and is expected in accordance with the specifications of the tightness of nuts and bolts.

Click Adjustable Torque Wrench

In this model the desired tightening moment can be adjusted (Adjustable) by adjusting the size of the firmness on the torque wrench. And it's easier to use than a type of deflecting beam. Because we don't need to look at the scale when tightening, we only need to hear a click if the tension has reached the desired level.

In this model there are types of settings for the rotation, including:

1 clockwise direction (Clockwise rotation)

2 clockwise or counterclockwise (Clock wise & counter clock wise rotation)

Other types of torque wrench are now increasingly developing and varying with the progress of the times and the need for use. The following types of Torque Wrench that might be rarely found in industries in Indonesia include:

1. Adjustable Torque Wrench

2. Adjustable Torque Wrench with Flexible Head

3. Interchangeable Torque Handle

4. Digital Adjustable Torque Wrench

And the following are the types of torque wrench that might be rarely found in Indonesian industries, including:

1.  Pneumatic Torque Wrench

The pneumatic Torque Wrench is the Torque Wrench that the tightening power uses pneumatic assistance (compressed air) so that it helps operator users in tightening bolts and nuts. The moment released is adjusted to control the air pressure used. This tool is usually used in tightening large bolts (requires large tightening). Pneumatic Torque Wrench sometimes confuse the standard Impact tools because they are similar (almost the same). But these two tools are completely different from each other. Pneumatic torque wrench driven by gear continuously not by hammer impact. This is why this torque has very little vibration and is very good in accuracy. This key was first created in Germany in the early 1980s. Its capabilities range from 60 Nm to a maximum of 48,600 nm. The power source of this tool uses compressed air.

2. Hydraulic Torque Wrench

Hydraulic torque wrench is a tool designed to tighten the bolts precisely (according to specifications) using hydraulic power. The torque wrench is used for nuts either directly or in combination with sockets. The concept of a hydraulic torque was first introduced in the market around the early 1960s in an ancient form and several advancements have been developed by manufacturers and have since provided great advances in technology and also the use of tools that go beyond the original tool concept. This tool offers advantages such as lighter weight smaller fingers which fit the ability to run multiple devices simultaneously from one power pack, etc.

3. Electric Torque Wrench

Electric torque wrench is the torque wrench that the power of the power uses power / electric power, this torque wrench works properly, precision and accuracy are very good with a good & stable rotation speed, from several choices of models possessed this electric torque wrench has the ability of the moment from 60 Nm to 45,000 Nm complete with settings that stop automatically according to the desired moment (Nm), and usually this electric torque wrench is already with standard IP54 protection protection against moisture, dust and even rain.

4. Battery torque wrench (Battery / Cordless)

This type of torque wrench uses battery power that can be recharged again when the battery runs out. This model is a very simple model that can be used for many applications, especially for use in high altitude areas without having to make it difficult to provide the power / power source needed & to be able to be used for narrow confined areas. For this type of battery has the ability from 90 Nm to 4,000 Nm and is available with 2 (two) speed settings namely low rotation speed & high rotation speed.

5. Manual Torque Wrench (Multiplier)

The manual torque wrench has a very large capacity capacity from 200 Nm to 50,000 Nm. This type in the tightening process to achieve the right & accurate moment does not require power (Electricity, Hirdolic, Pneumatic, Battery, or anything else) but only requires manpower, This Manual torque has material strength / durability & very good function and application.
