13-Piece Jumbo Metric Hex Key Set (1.5mm 17mm) Extra Long Arm Ball End Allen Wrenches Heavy Duty CR-V Steel L-Keys for Automotive, Industrial & Machinery Repair

[Massive Metric Size Range] Most sets stop at 10mm. This 13-piece jumbo kit covers the full spectrum from precision 1.5mm up to a massive 17mm (1.5, 2, 2.5, 3, 4, 5, 6, 7, 8, 10, 12, 14, 17mm), handling heavy-duty bolts on cars, trucks, and industrial equipment. | [Extra Long Arm Leverage] Break loose stubborn or rusted fasteners with ease. The extended long-arm design acts as a breaker bar, providing superior torque and reach into deep, confined spaces like engine bays or machinery housings. | [25 Ball End Entry] The long arm features a ball-end tip that allows you to engage screw heads at a 25-degree angle. This speeds up work in blind spots or tight corners where a straight-on approach is impossible. (Note: Ball end typically on sizes 3mm and larger). | [Industrial Strength CR-V Steel] Forged from premium Chrome Vanadium Steel (CR-V) and heat-treated for maximum hardness (HRC 50-58). The surface features a corrosion-resistant finish to prevent rust and oil buildup, ensuring longevity in harsh garage environments. | [Portable Storage Case] Keep your heavy tools organized. The set comes in a durable, labeled carrying case that locks each key securely in place. High-visibility size markings make it easy to identify the right tool instantly, preventing loss.
