The Sealey 21mm 1/2" Drive Deep Hexagon WallDrive Socket is sized for heavy-duty fastening applications. The 21mm measurement is commonly found in commercial vehicle wheel nuts, heavy machinery, and industrial equipment, making this socket essential for workshops and professionals working with larger vehicles and plant machinery. This socket is cold-forged from premium Chrome Vanadium steel, then hardened and tempered to provide exceptional strength for high-torque applications. The WallDrive® socket configuration is particularly valuable when working with larger fasteners, gripping bolts on their flat sides rather than corners to deliver superior torque transfer whilst minimising the risk of rounding, even on corroded or over-torqued fixings common in commercial vehicle maintenance. The mirror-polished chrome finish provides excellent corrosion resistance and makes post-job cleaning straightforward. The knurled ring ensures secure handling even when your hands are covered in oil or grease, whilst the deep hexagon design allows you to access recessed fasteners and work with extended bolt threads that standard-length sockets cannot accommodate. Features and Benefits: • 21mm metric size perfect for commercial vehicle wheel nuts and heavy machinery • 1/2" drive fitting for use with ratchets, breaker bars, and torque wrenches • Cold-forged Chrome Vanadium steel for professional-grade durability • WallDrive® technology reduces fastener damage and improves torque transfer • Deep socket design for accessing recessed and extended fasteners • Knurled grip ring for confident handling in challenging conditions • Lifetime guarantee for lasting workshop value Specifications: Brand: Premier Depth: Deep Drive: 1/2"Sq Material: Chrome Vanadium Nett Weight: 0.16kg Size: 21mm
