The Sealey AK5816M is a professional 16-piece impact socket set designed for demanding automotive and mechanical applications. This comprehensive metric socket collection features deep WallDrive® sockets with 1/2" square drive, manufactured from hardened and tempered Chrome Vanadium steel for exceptional durability and performance. The WallDrive® design is engineered to grip fasteners on their flat sides rather than the corners, allowing up to 30% more torque transfer whilst significantly reducing the risk of rounding off fixings. This makes the set particularly effective for working with corroded or tight bolts commonly encountered in vehicle maintenance and heavy machinery repair. Each socket benefits from a phosphate finish that provides enhanced corrosion resistance, essential for tools regularly exposed to workshop environments and automotive fluids. The deep socket configuration offers extended reach, making them ideal for accessing recessed nuts and bolts on suspension components, engine assemblies, and chassis work where standard length sockets cannot reach. The set covers a comprehensive range from 10mm through to 32mm, providing the socket sizes most frequently required by mechanics, plant operators, and general engineering professionals. All sockets are supplied in a durable storage case for organised transportation and workshop storage, and are backed by a lifetime guarantee for long-term peace of mind.
