Sealey 3/8" Drive Hexagon Impact Socket Metric

The Sealey 3/8" Drive 12mm Hexagon Impact Socket is an extremely versatile size found throughout automotive, industrial, and mechanical applications. The 12mm variant is particularly common for wheel bolts on many vehicles, suspension components, brake hardware, and a vast array of engine and chassis fasteners, making it one of the most frequently reached-for sockets in any professional toolkit. Constructed from high-quality chrome vanadium steel through precision drop-forging, this impact socket provides exceptional strength and longevity. The WallDrive® configuration makes contact with the flat sides of fasteners rather than the corners, delivering superior torque transfer whilst dramatically reducing the risk of rounding bolt heads. Hardened and tempered to withstand the demands of impact wrench use, it's built to professional standards. The phosphate finish offers excellent protection against corrosion and wear, ensuring reliable performance even after years of intensive use. Its 3/8" square drive ensures compatibility with all standard air impact tools, making it an essential component of any comprehensive socket set. Backed by Sealey's lifetime guarantee, this workhorse socket delivers exceptional value.
