I made this table after too many times finding myself grabbing a standard wrench and finding the nut is metric, or vicey-versey. This table lets me know which wrench to grab next. After 20 years, Detroit still puts out cars with hybrid fasteners!

It may be good to know that tools - as well as fasteners - are not at the exact size but have a range of play designed into them for guaranteed engagement during use. This means that you can actually take the "wrong" size wrench and have a tight fit on the fastener, reducing the chance of rounding a nut. Again, this is where the table comes in handy.
