Sockets are commonly used tools in hardware tools. In fact, socket wrenches are also a kind of sockets. Different socket categories have different opinions. For example, different power drives can be divided into manual sleeves, electric sleeves and pneumatic sleeves. The socket wrench is an extension of the socket and belongs to the scope of the manual socket, so its function is to fix or remove the screw. Especially for some screws with special positions, such as deep recesses or low positions.
Socket wrenches are developed and evolved on the basis of the original traditional wrenches, and are more suitable for modern projects. They can be installed in different combinations according to different situations to meet the needs of the project. The current sleeve has many advantages in application, and it is small in size and easy to operate. It can be used on any working surface. The use is not affected by factors such as time and environment. This realizes all-day operation and does not occupy Advantages such as construction period.
When purchasing a socket wrench, there are two main aspects of data that need to be referred to: one is to look at the surface, and the other is to look at the inside. The first thing to look at is whether there are nicks and scratches on the surface of the sleeve. Although many unscrupulous merchants now sell old sleeves as new products after electroplating, the original scratches and burrs are not easy to cover up. Another consideration for purchase is the strength and torsion of the inner wall of the sleeve itself. This detection can be achieved by special tools. In this way, it can be detected whether the raw material of the sleeve meets the standard. In addition, the sleeves of different materials should be selected according to the power. Generally speaking, the sleeves with weaker hardness can be selected for the manual sleeves, but the stronger sleeves should be selected for electric and pneumatic.
Now the sleeve production technology is relatively mature, and the product can basically meet the usual production needs, but in many special occasions, it will also encounter inappropriate product specifications. Such situations need to be ordered from the manufacturer in advance.
