18. The features description of torque screwdriver
¼”Bit:
It applies to all kinds of ¼” bit according to user needs.
Locking ring:
Locking the torque setting value. Using it not change.
Ergonomic comfort rubber grip
Ergonomic comfort rubber grip let users feel comfortable and not slippery.
Scale:
Differential scale display is easy to read. Users set the torque value accurately and quickly.
1. The product use bead-groove click structure. When the torque reaches to the setting value, it will unlimited click to avoid excessive use of locking and two-way use.
2. Using aluminum alloy body can make tool lightweight.
3. The torque screwdriver use two thrust ball bearings and one steel ball bearing to reduce effectively the friction coefficient and achieve more stable torque value.

19. The six main factors affect the quality of torque wrench
1. The tube body:
Overall special treatment is anti-wear better to get the accurate torque value.
2. Spring:
The different materials of springs have different fatigue resistance. The general torque wrench is made of ordinary materials. KT product has High Quality Alloy steel and is better than traditional steel wire. Heat treatment then forming. It makes sure the quality (the k-value of spring) and using life of spring.
3. The lubricating oil:
When the tube body and the parts are working to produce friction coefficient. Using good lubricating oil can effectively reduce friction coefficient. (KT products use imported high-class lubricating oil to increase the using life and lubrication, then It will reduce the friction coefficient.

20. 4. Fabrication technology:
The torque wrench is composed of a number of precise parts. The staff fabricators will affect the products quality. The KT staff fabricators must be subject to relevant training courses, then they can fabricate products to ensure the product quality.
5. Parts tolerance design:
Each part has a tolerance. It is an important lesson to learn how to control the product tolerance in a appropriate range. Each part of KT torque wrench has been meticulous thinking and computer design to processing to meet the quality of the product which is higher than the same business.
6. The calibration technology and equipment:
In order to ensure the quality of torque wrench, we have to calibrate the torque value when it is leaving the factory. The all of KT products meet DIN-ISO We use three-point calibration with the automatic calibration machine to avoid human error calibration. It makes sure the quality of torque wrench.

21. Using Notes
After you work done with torque wrench, you need to adjust the torque value to zero to avoid Long-term oppression of spring to elastic fatigue. It affects torque accuracy.
Avoid using the torque wrench as a dismantling tool to cause the damage of the component.
Avoid throwing heavily.
When using exception. First, you can check whether the abnormal ratchet head parts. If they have no abnormal, it could be damage the internal structure of parts. Please notify maintenance unit to fix it.
After general torque wrench used about 5,000 times, it needs to calibrate torque value. After KT torque wrench used about 10,000, it just need to calibrate torque value.
In order to ensure the accuracy of the torque value, please don’t disassemble any part in the tube to avoid any trouble when using the tool.
