I am losing my mind! Bolt threads etc

[MikeRock]

Is this the thread, on the bottom of the punch?  It is from their website, but no thread data.

I wrote the European distributor.  They contacted the maker and said, "The manufacturer states that the thread is "M10", I hope this helps."

She did not specify the thread pitch.

I´m updating here cause I have an Astor M5 on my bench for restoration - the inner thread is metric M10x1.5 (at least on mine). So the information MikeRock got from the distributor is correct.

So if you need a cheap tool adapter for M6 or M8 tools / dies then this could be an option:

Hope this helps
