The Capri Tools Hex and Torx Key Wrench Set is constructed of premium S2 steel, a steel used only for premium hand tools for its shock-resistant and tough properties, outperforming Chrome Vanadium and lesser alloy steels, and therefore our wrenches maintain their shape with heavy use. The hex key wrench features a hex end and a ballpoint end. The Torx key wrench has two Torx ends. Hex and Torx ends feature chamfered edges for easy insertion onto fasteners. Ballpoint end can enter a fastener at up to a 25° angle, reaching hard-to-reach areas. Our flexible single piece storage case opens flat so you can easily access your wrenches, and it folds and latches securely for easy carry and storage. The wrenches are finished with corrosion resistant smooth black oxide.
