Thanks for creating this spreadsheet. It has saved me the time of recreating it from a similar Mathcad file I was using.
I was wondering if you could elaborate on what the thread depth variable is in the sheet. I took it as 0.600 X P for metric fine threads. I found this at: http://www.colinusher.info/Livesteam/mewdata.html#data
Is this correct?
