DIYers, cyclists, furniture assemblers, and light-industrial technicians all run into this problem — and a short-arm key just makes it worse. These extra long metric Allen key wrenches are built specifically for those tight-access situations.\u003c\/p\u003e\n\u003cp\u003eEach wrench features a ball-end tip on the long arm and a standard hex tip on the short arm, machined from alloy steel with a black oxide finish. Sizes span 1.5 mm (approx. 0.059 in) through 10 mm (approx. 0.394 in), with an additional Flat Head 5 mm variant. The extended shaft length — typically 100–200 mm depending on size — gives you the reach and leverage that compact keys lack.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include tightening M3–M10 socket-head cap screws on bicycle derailleurs and brake calipers, adjusting set screws on furniture cam locks and shelf brackets, and servicing recessed fasteners on power tools, 3D printers, and CNC fixtures — all scenarios where a long-arm hex key with ball end access is the right tool for the job.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e \u003cstrong\u003eCompatible with:\u003c\/strong\u003e ISO metric socket-head cap screws (DIN 912), set screws (DIN 913\/916), and grub screws — sizes M1.5 through M10.

The standard hex end (on the short arm) provides a full flat-face contact for maximum torque when tightening or breaking loose a fastener. Use the ball end to start or run down a screw quickly, then switch to the short arm for final torque.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhich size should I choose for M4, M5, or M6 socket-head cap screws?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eFor ISO metric socket-head cap screws (DIN 912), the hex key size matches the socket width across flats: M4 screws use a 3 mm hex key, M5 screws use a 4 mm hex key, and M6 screws use a 5 mm hex key.

At high angles, the contact area between the ball tip and the fastener socket is reduced, which can round out the socket if excessive force is applied.

This is useful when you need the extended reach of the long arm but require the full torque capacity of a standard hex tip — for example, when tightening a 5 mm socket screw in a deep recess that is still accessible straight-on.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I choose the right pack quantity?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eIf you need a single size for a specific repair, a 1 or 2 PCS pack is the most economical choice. For workshop stocking or if you frequently lose or misplace small hex keys, the 5, 10, or 15 PCS packs offer a lower per-unit cost.
