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.

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 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 impact socket set is accompanied by a heavy-duty 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 120pcs SAE and Metric impact sockets, 5 socket adapters, 3 impact extension bars (3/8DR) and 2 impact extension bars (1/2DR), offering a versatile selection for various mechanical tasks.
