Torque wrenches are also called torque wrenches, torque wrenches, and torque adjustable wrenches. They are a type of wrench. According to the power source can be divided into: electric torque wrenches, hydraulic torque wrenches and manual torque wrenches; manual torque wrenches can be divided into: preset type, dial type and digital display.
The main characteristic of the torque wrench is that the torque can be set and the torque can be adjusted.
Torque wrench application:
Torque wrenches are fastening bolts. High-strength bolts can be classified into torsional shear type and large hexagon type. The national standard torsion type high-strength bolts are M16, M20, M22, and M24. Now, there are also non-standard M27 and M30 types. The national standard big hexagonal high-strength bolts are M16, M20, M22, M24, M27, and M30. In general, the tightening of high-strength bolts must be tightened and then tightened, and strict torque requirements must be met at each step. For the initial tightening and final tightening of large hexagonal high strength bolts, constant torque wrenches must be used.
The torque wrench can be tightened and tightened. Its use is to adjust the torque first and then tighten the bolt.
Constant torque electric wrench features:
Easy to operate, save time and effort, adjustable torque.
Torque Wrench Options Reference
1. The ergonomic design of the handle is optimized to hold comfort and greatly reduce the fatigue caused by high-intensity operation.
2, double scale, can accurately set the torque value.
3. When the set torque value is reached, a clear signal is heard and a slight vibration can be felt on the handle.
4, the lock ring close to the tiger's mouth, can avoid misoperation to change the set torque value.
5, wrench length: 990MM.
6, drive the size of 3/4 inches.
7, the minimum scale interval 1.
8. The applied torque should be within 40% to 90% of the torque range of the wrench.
9. Press the lock nut.
