Vevor 3/8" Drive Impact Socket Set, 48 Piece Socket Set Sae 5/16" -3/4" And Product Details Specifications Cr-V Industrial-Grade Alloy Steel: Crafted from premium impact-grade alloy steel, our 3/8 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 48pcs 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.
