DIYers, cyclists, and workshop technicians who work with metric socket-head cap screws need a reliable long-arm hex key that fits precisely and won't round out under load. This metric Allen hex key set covers sizes from 1.5 mm (0.059 in) to 22 mm (0.866 in), giving you the right tool for virtually every metric hex fastener you'll encounter.\u003c\/p\u003e\n\u003cp\u003eEach key is machined from CR-V (Chrome Vanadium Steel) and features a long-arm L-shape design. The extended arm provides extra reach into deep recesses, while the short arm acts as a high-torque driver. Sizes span 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 17 mm, 19 mm, and 22 mm. Available in packs of 1, 2, 4, 5, 8, or 10 pieces so you can stock exactly what you need.\u003c\/p\u003e\n\u003cp\u003eTypical applications include assembling flat-pack furniture with M3–M8 socket screws, adjusting derailleur limit screws and stem bolts on bicycles, tightening grub screws on motor shafts and couplings in light machinery, and servicing automotive interior trim panels that use metric hex fasteners. The long-arm format is especially useful for hex key wrench for tight spaces where a standard key cannot swing a full arc.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e Compatible with all standard metric socket-head cap screws (ISO 4762 \/ DIN 912), set screws, and grub screws using hex drive.

When you flip the key and use the short arm as the driver, the longer lever arm of the handle side significantly increases the torque you can apply — useful for loosening seized fasteners.

For typical DIY and light-to-medium professional use — furniture assembly, bicycle maintenance, machinery servicing — CR-V hex keys perform reliably. For sustained industrial torque beyond the tool's rated capacity, a torque-limiting tool is recommended to avoid overloading any hand key.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill these hex keys rust or corrode over time?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eCR-V steel has moderate corrosion resistance, but it is not stainless.
