These screws are inspired by DINE6921 metric screws with hex flange head and they have metric fine pitch threads. The longer screws have partial threads. My inproved thread design has an accuracy of 2.5µm and should fit without tolerances. Please print with low layer height, e.g. max. 0.15 mm for a 0.4 mm nozzle.
