Why this one
Extra long arm
The extra long arm gives more reach and more leverage, which helps break corroded or thread-locked fasteners free without damaging the hex recess.
Two working modes
Use the short side in the fastener for power, or the long side for reach, and flip the key around as conditions change.
Sizes 1.5 to 10 mm
Sold individually in metric sizes from 1.5 to 10 mm, and each key is individually marked for size.
Chrome vanadium, black phosphate
Made from chrome vanadium steel with a black phosphate finish.
Read the full description
When a job demands one specific metric size and real leverage behind it, this Teng Tools 10 mm L-wrench puts both in your hand without the weight and clutter of carrying a full set.
The extra long arm measures 224 mm (8.8 in) overall. That additional length is not just about reach — it directly increases the torque you can generate by hand, making it easier to break corroded or thread-locked fasteners free without damaging the hex recess. Whether you are working on motorcycle engine covers, bicycle crank bolts, industrial hinges, or CNC fixtures, the longer arm keeps you in control.
Weighing 177 g (6.2 oz), the wrench is still compact enough to carry in a pocket or tool pouch. The L-shape gives you two working modes: short side in the fastener for power, or long side in the fastener for reach. Flip it around as conditions change and keep working without hunting for a second tool.
This is a single 10 mm wrench sold individually. It is the smart purchase when you need to replace one lost or worn piece from an existing collection, stock a dedicated service kit with only the sizes a specific machine requires, or simply keep an extra on hand because this is the size that always seems to disappear from the drawer first.
