The Sealey 16 Piece 1/2" Drive Hexagon Impact Socket Set is a professional-grade socket set engineered for use with impact tools in automotive and mechanical applications. Manufactured from Chrome Vanadium steel, each socket is hardened and tempered to withstand the high-torque demands of impact wrenches whilst maintaining dimensional accuracy under repeated use. The phosphate finish provides enhanced corrosion resistance, extending the working life of the sockets in demanding workshop environments. The set features WallDrive® socket technology, which distributes force around the flats of the fastener rather than across the corners, allowing up to 30% more torque transfer to the fixing whilst reducing the risk of rounding. This comprehensive 16-piece set covers metric sizes from 10mm through to 32mm, providing the range required for most automotive, plant machinery and general engineering tasks. The sockets are supplied in a storage case for organised tool management and transportation
