Cr-Mo Industrial-Grade Alloy Steel: Crafted from premium impact-grade alloy steel, our 3/8" & 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 59pcs 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: Includes 1/2" SAE deep sockets - 3/8"、7/16"、1/2"、9/16"、5/8"、11/16"、3/4"、13/16"、7/8"、15/16"、1"、1-1/16"、1-1/8"、1-1/4"; 1/2" metric shallow sockets: 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 23, 24, 27, 30, 32mm; 3/8" SAE deep sockets: 5/16"、3/8"、7/16"、1/2"、9/16"、5/8"、11/16"、3/4"、13/16"; 3/8" metric shallow sockets: 6、7、8、9、10、11、12、13、14、15、16、17、18、19mm, two extension bars and 2 adapters.
