DIYers, mechanics, and assembly technicians who work with metric fasteners daily know the frustration of stripped sockets and wasted time. This 9-piece metric Allen key set with ball end tips is built to solve exactly that problem — giving you off-angle access up to 30° without losing torque.\u003c\/p\u003e\n\u003cp\u003eThe set includes nine hex keys covering sizes 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, and 10 mm (approximately 0.059 in – 0.394 in). Available in two material grades — Chrome Vanadium (CR-V) for everyday versatility and S2 Alloy Steel for higher-torque applications — and in Medium Length or Extra Length configurations to match your reach requirements.\u003c\/p\u003e\n\u003cp\u003eWhether you're assembling flat-pack furniture, adjusting stem bolts on a road bike, servicing HVAC equipment, or tightening set screws on industrial machinery, this metric hex ball end wrench set covers the sizes you'll reach for most.
