- Large arc design: The head of this socket adopts a large arc shape, which has a larger contact area with the bolt or nut. It can evenly distribute the acting force, reducing the damage to the edges and corners of the bolt or nut during the tightening or loosening process. At the same time, it can also provide more stable torque transmission to prevent slipping.

- Extended structure: Compared with ordinary pneumatic sockets, it is longer in length and can easily reach into narrow or inaccessible spaces, such as the interior of an automobile engine, the depths of mechanical equipment, etc., making it convenient to operate the bolts or nuts in these positions.
