Brand: GALAX PRO

A hex key, Allen wrench or Allen key, is a simple tool used to drive bolts and screws with hexagonal sockets in their heads.
The Allen wrench 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.
Features
The tool is simple, small and light.
The contact surfaces of the screw or bolt are protected from external damage.
There are six contact surfaces between bolt and driver.
Very small bolt heads can be accommodated.
The tool allows the use of headless and recessed-head screws.
The screw can be held by the key while it is inserted into its hole.
The torque applied to the screw is constrained by the length and thickness of the key.
Either end of the tool can be used to take advantage of reach or torque.
The tool can be reconditioned using an electric grinder by removing the worn-out part near the end.
High torque is more likely to damage an internal socket/key than an external hexagon head/wrench.
It is much more difficult to turn a damaged internal fastener than an external one.
