Allen Key M4 FUH0950 919

A Hex Key or Allen key is a simple tool, used to drive bolts and screws with hexagonal sockets in their heads.nThe tool is usually formed of a single piece of hexagonal rod of hard steel, with blunt ends that are meant to fit snugly into the screw’s socket, bent in an “L” shape with unequal arms. The tool is usually held and twisted by the long arm, creating a large torque at the tip of the short arm. Reversing the tool lets the long arm reach screws in hard-to-reach places.nEach key is meant to be used with screws of a specific socket size, with rather tight tolerances; so, the tool is commonly sold in kits that include half a dozen or more keys of different sizes. Usually, the length of the key increases with the size of the socket, but not necessarily in direct proportion.n
