Standard Socket
Its surface is generally bright silver, and the material is forged from chrome-vanadium steel (Cr-V). A socket is the most convenient, flexible, and safe tool for removing bolts. Using a socket to remove nuts does not easily damage the edges of the nuts. However, it is necessary to choose the appropriate socket head based on the size of the working space and the bolts or nuts. It is generally used in conjunction with a ratchet wrench or an L-shaped socket wrench.
Pneumatic Socket
It is specially designed for use with pneumatic impact wrenches. Ordinary sockets are forbidden for use with pneumatic impact wrenches because when the wrench is operating, it generates extremely strong instantaneous impact forces. Ordinary sockets have thin walls, and CRV material can easily crack when heated, which may cause the plating on ordinary sockets to crack and spall, potentially injuring people. The pneumatic socket, on the other hand, is made of chrome-molybdenum steel alloy and its wall thickness is increased in the manufacturing process, while strength is reduced and toughness is enhanced, allowing it to withstand harsh working environments.
Ordinary sockets are prohibited from being used as a substitute for pneumatic sockets, but pneumatic sockets can temporarily replace ordinary sockets. However, each has its own specialty, so it is best if you can have both ordinary sockets and pneumatic sockets.
