*KeyFeatures *Cr-Mo Industrial-Grade Alloy Steel: Crafted from premium impact-grade alloy steel, our 1/2 impact socket set with Cr-Mo 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 34pcs 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 deep sockets 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm.
