**Magnetic Function**: With built-in magnetic components, it has a strong adsorption force on 1/2-inch specification twelve-angle bolts and nuts. When used in high-altitude operations, operations on vertical surfaces, or in narrow spaces, it can adsorb the fasteners, preventing them from falling off, avoiding the loss of parts, ensuring operational safety, and meanwhile improving the accuracy and efficiency of the operation.

**Extension Rod Design**: This design enables the socket to be flexibly extended in length through the extension rod. Users can select extension rods of different lengths to connect with the socket according to their actual work requirements. As a result, it can reach positions that are difficult for ordinary sockets to access, such as bolts in some deep holes, bolts in narrow spaces, or for connecting longer bolts, greatly expanding the scope of application and facilitating operations in complex equipment structures.

**Long Socket Structure**: The long socket itself provides a better leverage effect, making the operation more labor-saving. At the same time, the longer socket can also better adapt to some special working scenarios, such as the need to pass through a long shaft or pipeline to tighten or loosen the bolts, reducing the difficulty of operation caused by space limitations.

**Operation Convenience**: It is very easy to install on a pneumatic wrench. Operators can easily tighten and loosen the bolts by controlling the switch of the pneumatic wrench. This operation method is simple and easy to understand, without the need for complex skills or a large amount of physical effort, effectively reducing the labor intensity of the operators and improving the comfort and convenience of the work.
