Re: Copying micro-screws?
I would have thought so, Paul, we are talking about German engineering here! However, I have scoured for references to thread forms since the metric ISO was apparently agreed in 1947, but even obsolete European/Swiss screws from the early 20th century have pitches around 0.35mm for something with a major diameter this small. I found the 'Progress' thread from watchmaking was closest in specification, which I suppose is possible, but the head is unusual too (much like in watchmaking, actually).
I have seen in my searches in the forum that there are detailed old reference books around on thread forms so it may be that it is a special alloy thread and designated in some obscure specification.
