The Quadruple MicroSpeeder is a single tool that will fit the four most frequently used metric fasteners. Its clever design allows you to use it on nuts and bolts M6, M8, M10 and M12 with the 10, 13, 17 and 19mm rings. The ratcheting function with 72-teeth inner gear ring means the ratchet is still effective with only 5° movement. A forward/reverse lever gives the option for clockwise and anticlockwise rotation. The body of the spanner is CrV steel with double nickel-plating and single matt-finished chrome-plating. Total length 210mm.
