6 mm - M3 hex socket for quad nylon nuts and spacers

This is basically a simple hexagonal socket suitable to tighten nuts or spacer of flight control and distribution board quadcopters.
External diameter is 9.5 mm in order to don't interfere with other PCB components.
Interference free on CC3D FC board!
Intentionally designed without arms in order to prevent over torque on nut and screw threads.
A small device to put in your quad toolbox!
