Off topic as hell hopefully, but "Why we lubricate threaded fasteners was a semi recent submission & it's had surprising uhh sticking power in head. Lubrication overcomes a lot of friction that can create variability in tensioning. The standout example was giving students a bunch of torque wrenches & telling them to fasten a bolt, & then measuring the applied tension. And folks getting absurdly different numbers. The lubrication is there to allow the torque to consistently get applied. There could be all kinds of issues here, but this lesson on the difficult of bolting things consistently was interesting on its own & perhaps apropos. https://news.ycombinator.com/item?id=38921339 https://news.ycombinator.com/item?id=38921339 https://reliabilitysolutions.net/articles/why-do-we-lubricate-threaded-fasteners/ https://reliabilitysolutions.net/articles/why-do-we-lubricat...
