*KeyFeatures *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: 678910111213141516171819mm, two extension bars and 2 adapters. ******************************************************************************************************* *Specifications Item Model Number: SX1238MSSD590 Quantity: 59 PCS Material: CR-MO Alloy Steel Hardness: HRC42-48 Storage Box Size: 20.1 x 16.1 x 2.6 in / 510 x 410 x 65 mm Net Weight: 23.2 lbs / 10.52 kg ******************************************************************************************************* *Pakcage Content 14 x 1/2" SAE Deep Sockets 18 x 1/2" Metric Shallow Sockets 9 x 3/8" SAE Deep Sockets 14 x 3/8" Metric Shallow Sockets 2 x 3" Extension Bars (1/2"dr, 3/8"dr) 2 x Socket Adapters (1/2"F to 3/8"M, 3/8"F to 1/2"M) 1 x Toolbox 1 x User Manual
