Siegen 3/8" Drive Deep Hexagon WallDrive Socket Metric

The 18mm 3/8" Drive Deep Hexagon WallDrive Socket represents one of the larger sizes in the 3/8" drive range, ideal for substantial automotive fasteners, machinery components, and light commercial vehicle applications. This deep profile socket provides the extended reach necessary for recessed bolts on driveline components, larger suspension assemblies, and structural mounting points. The 18mm size sits at the upper capability of 3/8" drive systems, handling significant fasteners whilst maintaining the versatility of the mid-sized drive format. Engineered from Chrome Vanadium steel and heat-treated for enhanced durability, this socket withstands the higher torque loads associated with larger fasteners. The WallDrive® socket configuration becomes particularly valuable at this size, where the increased torque requirements make fastener protection critical—by gripping walls rather than corners, the design dramatically reduces the risk of rounding even when applying substantial force to remove seized or overtightened bolts.
