The Sealey 11 Piece 3/8" Drive Deep Bi Hexagon WallDrive Socket Set Imperial is a professional-grade socket set designed for working with imperial fasteners in challenging applications. This comprehensive set provides essential sizes for automotive, machinery, and equipment maintenance where deep reach is required to access recessed nuts and bolts. Manufactured from cold-forged Chrome Vanadium steel, these 12-point sockets are hardened and tempered to deliver exceptional strength and durability under demanding workshop conditions. The fully polished mirror finish not only provides excellent corrosion resistance but also makes cleaning easier after use in dirty or oily environments. The standout feature of this set is Sealey's WallDrive® configuration, which delivers an additional 30% more torque handling power compared to traditional socket designs. This advanced geometry distributes force more effectively around the fastener, reducing the risk of rounding off bolt heads whilst providing superior grip. Each socket features a knurled ring that offers extra purchase when handling them with oily or greasy fingers, a practical consideration for real-world workshop use. The set covers 11 essential imperial sizes from 5/16" through to 15/16", making it ideal for mechanics working on American vehicles, plant operators maintaining imported machinery, or engineers servicing equipment manufactured to imperial specifications. All sockets are supplied organised on a convenient socket rail for easy storage and quick size identification, and are backed by a lifetime guarantee.
