Our impact socket set provides the sizes needed for smooth transitions between sockets. Our impact socket adapters are made of steel, offering high hardness, good toughness, and strong impact resistance, maintaining performance over long-term use. Each socket adapter features a spring-loaded ball bearing that securely locks in place to prevent displacement or disconnection during use. The surface of the impact socket adapters is treated with phosphate coating to enhance hardness and corrosion resistance, reducing the risk of rust with extended use. This impact socket adapter set is designed for use with drivers, wrenches, and wheel nuts. The adapters allow easy conversion and are highly compatible with pneumatic tools, electric tools, and other driving tools.
