Whether you're a cyclist adjusting stem bolts, a furniture assembler working in tight corners, or a maintenance tech servicing industrial equipment, this long-arm ball end Allen wrench gives you the reach and angle flexibility to get the job done without rounding out fastener heads.\u003c\/p\u003e\n\u003cp\u003eEach wrench is machined from S2 tool steel (chrome-vanadium alloy), hardened for durability and finished with a black oxide coating for corrosion resistance. The long arm provides extended reach into recessed bolt heads, while the ball end allows up to 30° off-axis engagement — ideal for angled or partially obstructed fasteners. Available in 14 metric sizes from 1.5mm (approx. 0.059 in) to 19mm (approx. 0.748 in), sold individually or in small packs depending on size.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include bicycle component assembly (stem, derailleur, brake caliper bolts), flat-pack furniture with hex socket screws, and light machinery maintenance requiring metric Allen keys. The L-shape design doubles as a torque multiplier — use the short arm for high-torque driving and the long ball-end arm for fast spinning in open runs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard metric hex socket (Allen) fasteners.

Common sizes for bicycles are 4mm, 5mm, and 6mm; furniture assembly typically uses 4mm or 5mm; larger machinery fasteners may require 8mm–19mm.

Smaller sizes (1.5mm–3mm) are suited for low-torque precision fasteners; larger sizes (8mm–19mm) can handle significantly higher torque loads.
