*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 13pcs 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 13pcs metric deep impact sockets: 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 21 mm, 22 mm, 24 mm. ******************************************************************************************************* *Specifications Item Model Number: SS217813A Impact Sockets Set: 13 Pieces Material: CR-V Alloy Steel Hardness: HRC42-48 Product Size: 11.93 x 6.02 x 2.28 in / 303 x 153 x 58 mm Net Weight: 6.83 lbs / 3.1 kg Deep Sockets: 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 21 mm, 22 mm, 24 mm ******************************************************************************************************* *Pakcage Content 13 x Deep Sockets 1 x Toolbox 1 x User Manual
