**Size Specification**: The 3/8-inch size is suitable for hexagonal bolts and nuts of corresponding sizes in a variety of medium-sized machinery, equipment, and some industrial scenarios with high precision requirements. It has strong versatility.

**Large Arc Design**: The unique large arc shape makes the contact area between the socket and the bolts or nuts larger than that of ordinary hexagonal sockets. When torque is applied, the force can be more evenly distributed on the corners of the bolts and nuts, reducing stress concentration and the risk of damage to the edges and corners of the bolts and nuts. This, in turn, prolongs the service life of both the tool and the workpiece.

**Pneumatic Drive**: Using compressed air as the power source, it can provide a stable and powerful torque output. Compared with manual sockets, it greatly improves work efficiency, especially suitable for batch operations. It can quickly complete the tightening or loosening of bolts, effectively reducing the labor intensity of workers.

**Convenient Operation**: When used in conjunction with a pneumatic wrench, the installation is simple and convenient. Just install the socket correctly on the pneumatic wrench, align it with the bolt or nut, and start the air source to operate. There is no need for complex operation steps, and the skill requirements for operators are relatively low.

**Wide Applicability**: With its large arc design, appropriate size, and pneumatic drive mode, this socket is applicable to various industries such as automotive maintenance, machinery manufacturing, and electronic device production. It can meet the requirements for tightening and disassembling bolts in different scenarios.
