It also includes 2 extension bars (3" , 8"), 1/4" drive ratchet handle, 1/4" universal joint, and 3/8" to 1/4" adapter.

·CR-V Industrial-Grade Alloy Steel: Crafted from premium impact-grade alloy steel, our 1/4" impact socket set with CR-V industrial-grade alloy steel offers exceptional enhancements in impact resistance and absorption. Through the utilization of vacuum heat treatment, the steel undergoes rapid heating and cooling processes, resulting in a polished and highly durable surface. This makes it well-suited for a wide range of operational environments.

·High Torque: Distinguished by its hexagonal drive design, which sets it apart from traditional designs lacking rounded corners, this socket tool set significantly reduces pressure exerted on fasteners during impact. As a result, it minimizes wear and effectively prevents bolt rounding and stripping.

·Easy-to-Read Size Markings: The size markings on these 55pcs impact driver socket set are meticulously laser-etched and rolled, ensuring effortless identification of socket sizes even in low light conditions.

·Convenient Storage & Transportation: The set is accompanied by a moderate-weight metal toolbox, providing convenient portability. The toolbox facilitates organized storage of the tools after use, eliminating the risk of unnecessary scattering or loss.
