About this tool

The Sealey 3/8" Drive 18mm Deep Hexagon Impact Socket handles medium to large fastening requirements across automotive, plant machinery and commercial vehicle applications. This 18mm variant provides the capability needed for substantial structural bolts, drivetrain components and heavy-duty mounting systems. Manufactured from drop-forged Chrome Vanadium steel using precision engineering techniques, this deep impact socket delivers professional-grade performance that withstands the rigours of daily workshop demands. The WallDrive® hexagon configuration grips fasteners on their flat sides rather than vulnerable corners, significantly extending both fastener and socket life whilst improving performance on worn or corroded bolts.
