US "hardware store" threads #43

Closed jernst closed 4 years ago

jernst commented 4 years ago

I'm having some difficulties identifying which of the entries in the very large (and excellent) table refer to which specific thread in which country.

  1. Can I suggest to add a paragraph in the README that explains how the "designator" naming convention maps to descriptions one might be able to find with a web search. Perhaps with links to corresponding Wikipedia entries.

  2. Specifically, I'm attempting to find a thread that matches what I get when I go to a US hardware store and buy 1/2in PVC pipes. e.g. this part. The README says the library covers UNC, which I believe this is (?), but I cannot find a suitable entry. This page seems to have the correct dimensions, but nothing in the tables seems to match this.

Seems the answer is G1/2, derived by guessing and trying :-)
