The HK-Metric Hex Key Set provides the nine most commonly used metric sizes (1.5mm to 10mm) in premium S2 tool steel. S2 steel is a shock-resistant alloy specifically formulated for hex keys, offering an optimal balance of hardness (HRC 58-62) and toughness — it will flex and spring back rather than snap under high torque. Each key features a black oxide corrosion-resistant finish and a color-coded vinyl sleeve that provides both finger comfort and instant size identification. The long-arm/short-arm L-key design provides access to recessed fasteners and high-torque leverage. The included folding organizer keeps keys securely in place and folds flat for toolbox storage.
