The Draper Expert 9 Piece Long Arm Colour Coded Hex Key Set is a professional metric hex key set designed for accessing deeply inset bolts and fasteners where standard tools cannot reach. Manufactured from hardened and tempered chrome vanadium steel, this long arm hex key set delivers the strength and durability required for demanding workshop and site applications. Each hex key features a polished chrome finish for corrosion resistance, complemented by a colour-coded powder coating that allows instant size identification. This colour coding system speeds up tool selection, particularly useful when working in poorly lit areas or when efficiency matters. The chamfered tip edges eliminate burrs and ensure smooth engagement with fasteners, reducing the risk of damaging bolt heads. The set includes nine metric sizes ranging from 1.5mm to 10mm, covering the most commonly used hex key dimensions for automotive work, machinery maintenance, furniture assembly, and general engineering tasks.
