First, the torque wrench is also called a torque wrench, a torque wrench, and a torque adjustable wrench. It is a type of wrench. It can be divided into: electric torque wound, pneumatic torque wrench, hydraulic torque wrench, and manual torque wrench; manual torque wrench can be divided into: preset, fixed value, dial formula, digital explication, sliding type, bending, bending, bending, bending, bending, bending, bending, bending, bending Formula and kg wrench.
Second, torque wrench product parameters:
Material: Carbon Steel
Place of Origin: Shanghai
Execution standard: national standard
Category: dial formula torque wrench
Model: dial -type torque wrench
Third, torque wrench application:
The torque wrench is a fastener bolt. The high -strength bolt can be divided into two types: twist -cut type and large hexagonal type. The national standard twist -cut high -strength bolt is M16, M20, M22, M24. Now there are two types of non -national standard M27 and M30 ; The national standard large hexagonal high -strength bolts are M16, M20, M22, M24, M27, M30 and other types. Generally, the tightness of the high -strength bolt must be tightened first and then tightened, and each step requires strict torque requirements. The first tightness and final tightness of the high hexagonal bolt must be used.
Fourth, torque wrench characteristics:
Easy to operate, save time and effort, and torque can be adjusted.
