The Draper 10 Piece 1/2" Drive Deep Impact Hex Socket Set is a professional-grade metric socket collection designed for use with impact drivers and wrenches. Each socket is forged from chrome vanadium steel, hardened and tempered to withstand the high torque loads generated by pneumatic and electric impact tools whilst maintaining dimensional accuracy. The chemically blackened finish provides corrosion protection for long-term durability in workshop and site environments. Each socket features a spring-loaded ball retention hole, ensuring secure attachment to the drive tool and preventing accidental socket loss during overhead or awkward-position working. This comprehensive 10-piece set covers the most commonly used metric hex sizes from 10mm through to 27mm, making it ideal for automotive repair, machinery maintenance, and general mechanical applications. The deep profile design allows access to recessed fixings and provides clearance for protruding bolt threads on longer fasteners. All sockets are supplied in a practical plastic storage case for organised tool management.
