What are the classifications of socket wrench set
Hexagonal socket wrench is the most common type of socket wrench, and it is commonly used in daily life. Therefore, it is the most commonly used socket wrench.
The twelve point flower shaped socket wrench, as the name suggests, is a socket wrench with twelve internal angles, each angle being equal and 30 degrees.
There are two types of flower shaped socket wrenches, which are E starting and T starting. E starting represents the flower shaped socket wrench, while T starting represents the flower shaped screwdriver head. Therefore, when choosing, everyone must pay attention.
There is a pointer on the pointer torque socket wrench, which can be used to determine the degree of bolt rotation based on the rotation angle of the pointer. But everyone must remember not to touch the pointer, otherwise it will affect its accuracy.
The pre-set torque socket wrench can set the desired rotation angle in advance, and when we rotate to the set torque position, there will be a "click" sound.
