Genius Tools Metric Extra Long Hex Key Wrenches
Genius Tools Metric Extra Long Hex Key Wrenches are L-shaped hex keys with a long arm built for reach. Use them when a hex socket screw sits at the bottom of a bore, behind a cover or deep in an engine or machine where a standard key will not get to it.
The series offers 20 metric sizes: 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 17 and 19mm. The long arm runs from 90mm on the 1.5mm key up to 360mm on the 19mm, and the short arm from 14mm to 38mm.
The long arm can also be used as a lever. Put the short end in the screw and pull on the long arm to apply extra force to tight or stuck screws.
All keys are made of Chrome Vanadium Steel. They suit mechanics, machinists and maintenance technicians who regularly work on deep-set metric fasteners.
