I just got around to noticing a table for using the threading indicator. The table is the usual listing of indicator readings versus thread pitch.
However I just noticed that the thread pitch column is labeled TPI and the threads listed are all imperial threads.. I have reason to believe that the lead screw is metric.
So my question is, where is the error? Is my lead screw wrong and I should have a Imperial or is the label wrong and no 9X20 was ever shipped with a imperial lead screw.
