Genius Tools Metric Hex Key Wrenches
Genius Tools Metric Hex Key Wrenches are classic L-shaped keys for hex socket screws. They are compact, simple and give plenty of torque, which is why they are used everywhere from machine tools and bicycles to flat-pack furniture and engines.
The series includes 21 metric sizes: 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 17 and 19mm. The long arm runs from 45mm on the smallest key to 180mm on the 19mm, and the short arm from 14mm to 36mm.
Each key gives you two working options. Put the short arm in the screw and pull on the long arm for maximum leverage to break a screw loose, or use the long arm in the screw to reach in and spin it quickly.
The keys are made of Chrome Vanadium Steel for strength and durability. Pick a single replacement size or build a complete metric range; SAE and extra long versions are also offered.
