3 8" Drive Hexagon Impact Socket Metric 3 8" 18mm

The Sealey 3/8" Drive 18mm Hexagon Impact Socket is a larger size commonly found in commercial vehicles, agricultural machinery, and heavy-duty industrial equipment. This 18mm variant is particularly useful for drivetrain components, larger suspension fasteners, heavy machinery bolts, and various applications where more substantial fastening is required beyond typical light vehicle work. Crafted from high-grade chrome vanadium steel through precision drop-forging, this impact socket provides exceptional strength for demanding applications. The innovative WallDrive® configuration makes contact with the flat sides of 18mm fasteners rather than the corners, distributing forces more effectively and significantly reducing the risk of rounding larger bolt heads. Hardened and tempered to withstand intensive use, it's engineered specifically for the high torque demands of impact wrench applications. The phosphate finish delivers superior protection against corrosion and wear, ensuring consistent performance even in harsh industrial or outdoor environments. Its 3/8" square drive ensures universal compatibility with standard air impact tools, providing reliable operation across diverse heavy-duty tasks. Backed by Sealey's lifetime guarantee, this robust socket delivers professional quality for demanding applications.
