Features of socket wrenches:
The socket wrench is a combined tool, which is often combined by a socket, a post, a rocker, etc. into a wrench when used. Commonly used socket wrenches have 13-piece sets, 17-piece sets and 24-piece sets, as shown in Figure 1-12. The socket wrench is suitable for disassembly and assembly of small, particularly concealed bolts or nuts. The sleeve part is similar to the end of a torx wrench and is made into a single piece. According to needs, different specifications of sleeves and various handles can be used for combination. For example, the movable handle can adjust the required moment arm; the quick handle is used to quickly disassemble bolts and nuts; at the same time, it can be equipped with a torque wrench to display the tightening torque, which has the characteristics of multiple functions, convenient use, safety and reliability.
