Sealey 3/8" Drive Hexagon WallDrive Socket Metric 3/8" 20mm

This 20mm socket addresses specific requirements in automotive and machinery maintenance, including certain brake components and suspension assemblies. The 3/8" drive size, whilst approaching its upper limit for this fastener size, provides excellent manoeuvrability where larger drive systems would struggle. Engineered from cold-forged Chrome Vanadium steel with subsequent hardening and tempering, this socket delivers the strength needed for demanding applications. The WallDrive® socket configuration's unique design grips fastener flats rather than corners, maximizing torque transfer whilst protecting against rounding damage. The mirror-polished chrome finish resists corrosion, and the knurled ring ensures secure handling in workshop conditions.
