Regarding your edit on ISO metric screw thread
Hello IP user! Thanks for contributing to Wikipedia! But I reverted your edit to ISO metric screw thread. Most importantly, I think the statement that needs sourcing is that the metric screw thread is one of the first ISO standards; in other words, the whole sentence. Neither of the words screw or thread occur in the ISO article. Furthermore, Wikipedia itself is not a source; if another article already provides a source for a statement, you shouldn't link to that article as a source. Rather, you can just copy the source from the other article and use it here as well. Digital Brains (talk) 10:01, 22 February 2019 (UTC)
