*KeyFeatures *Cr-Mo Industrial-Grade Alloy Steel: Crafted from premium impact-grade alloy steel, our 3/8" swivel 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. *Swivel Socket & High Torque: Swivel socket with flexible wobble allows you to cover a wider range of drilling. Distinguished by its hexagonal drive design, which sets it apart from traditional designs lacking rounded corners, this 360 degree swivel impact socket set significantly reduces pressure exerted on fasteners during impact. *Easy-to-Read Size Markings: The size markings on these 14pcs swivel 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 swivel socket 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 10pcs metric deep impact sockets: 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm.
