The Sealey 12 Piece 3/8" Drive Deep Bi Hexagon Socket Set is a professional metric socket collection designed for accessing recessed and deep-set fasteners. Featuring cold-forged Chrome Vanadium steel construction, these 12-point sockets are hardened and tempered to deliver exceptional strength and durability for demanding workshop applications. The WallDrive® socket configuration provides an additional 30% more torque handling power compared to traditional socket designs, distributing force more evenly across the fastener to reduce the risk of rounding. Each socket features a fully polished mirror finish for superior corrosion resistance, whilst the knurled ring design ensures a secure grip even with oily fingers—an essential feature for mechanics and technicians working in challenging conditions. This comprehensive set covers sizes from 8mm through to 19mm (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19mm), providing the range needed for common automotive, machinery, and general mechanical fasteners. The deep socket design makes this set particularly suitable for applications involving threaded rod, long bolt assemblies, and spark plug work where additional clearance is required. Supplied with a socket rail for organised storage and workshop efficiency, the set is backed by a lifetime guarantee. Ideal for professional mechanics, mobile technicians, and maintenance engineers requiring reliable access to deep-set fixings.
