*KeyFeatures *Cr-V Industrial-Grade Alloy Steel: Crafted from premium impact-grade alloy steel, our 1/2 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 23pcs 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. *Abundant Components: This comprehensive set includes an array of components, such as standard sockets 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", 15/16", 1".
