I would say it seems like most of the stuff I work on these days is metric fasteners. This includes vehicles, tractors and small engines. I am a land surveyor and our state DOT went all in on the metric system. That lasted just a few years and they switched back to English. I did a couple of jobs in metric and it was not to bad except leveling. I really struggled with the metric level rod. We had one long term job in design, started in English, changed to metric, changed back to English. That is spending the tax payers money wisely.
