The Sealey Premier 17 Piece 3/8" Drive Deep Impact Socket Set is a professional socket set designed for impact wrench applications across a comprehensive range of metric sizes. Manufactured from hardened and tempered Chrome Vanadium steel with a phosphate finish, this set delivers enhanced corrosion resistance for extended tool life in demanding workshop environments. The WallDrive® socket design is a key feature of this Premier set, allowing up to 30% more torque transfer to the fixing compared to conventional socket profiles. This reduces the risk of rounding fastener heads and provides more secure engagement on worn or damaged fixings. The deep socket configuration makes this set particularly suitable for accessing recessed nuts and bolts, or working with longer threaded fasteners on automotive, plant machinery, and general engineering applications. Colour-coded identification rings enable fast socket selection during time-critical jobs, whilst the included storage case keeps the complete 17-piece set organised and protected. Covering sizes from 6mm through to 24mm, this comprehensive socket range is ideal for mechanics, mobile engineers, and maintenance professionals working with impact drivers. The set is backed by a lifetime guarantee for long-term reliability.
