**Extended Design**: Compared with the ordinary 1/2 twelve-point pneumatic socket, the extended structure enables it to reach places that are difficult for ordinary sockets to access, such as the interior of the engine compartment, the deep parts of large mechanical equipment, etc. This design reduces the operational inconvenience caused by space limitations. For work scenarios where bolts and nuts are in relatively deep positions, it can easily complete the tightening or disassembly tasks, greatly improving the accessibility and convenience of operation.

**Twelve-point Precise Fit**: The 1/2-inch twelve-point specification can closely fit the twelve-point bolts and nuts of corresponding sizes. The multi-surface contact method makes the torque distribution more uniform. When a large torque is applied, compared with the hexagonal socket, it is less likely to damage the edges and corners of the bolts and nuts, ensuring a stable force transmission between the tool and the workpiece during the operation and improving the reliability and safety of the operation.

**Universal Joint Flexibility**: The unique universal joint structure endows the socket with the ability to rotate freely within a certain angular range. Even if the bolts and nuts are in complex angles or positions, such as inclined bolts in narrow spaces or bolts on irregular structures, there is no need to adjust the overall position of the tool. The operation can be achieved only by the rotation of the universal joint, which greatly enhances the adaptability of the tool in complex working environments and improves work efficiency.

**Efficient Pneumatic Power**: As a pneumatic tool, it uses compressed air as the power source and can provide a powerful and stable torque output. Compared with manual tools, it is faster when tightening or loosening bolts and nuts, greatly shortening the working time.
