Description

PDF

These screws are inspired by ISO 8765 metric screws and they have metric fine pitch threads. They come with hexagonal heads, that are slightly bevelled on one side and contain a washer-like elevation on the other side. 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.
