Allen Key M 4 Length 350 Mm

The mechanical system in Sky Fox series full-fuselage helicopters is located on a base plate, held in place by four or six brackets which in turn are fixed to the fuselage floor using M 4 socket-head cap screws.
This long M 4 allen key is ideal for those hard-to-reach screws.
