Bolt Depot's "Fastener Type Chart" is exactly what I need so as not to sound like a total idiot when I come up with some interesting project requiring a certain type of fitting and hie myself to the DIY shop to try to explain what I need to the clerk. More practically, it also gives you the right search terms to use to find the dingus you need.
