Precision machined brass
The width of the nut (flat to flat) is 3mm. A 3mm wrench is required for 2.0mm hex nuts. The 2.0mm dimension refers to the diameter of the threaded hole in the nut.
Sometimes we forget how good some of our replacement parts are! A perfect example is our 2.0mm Brass Nuts. They replace the Pocher provided 2.0mm nuts which are too wide to be prototypical and often have unsightly burrs. Ours are 0.4 mm narrower and are imported from Germany.
