Know your bolts

MAKE contributor James Floyd Kelly wrote in with a tip on a cool resource:

Found some GREAT information on Bolt Depot’s homepage, including this printable poster that displays all the different bolts and nuts and connectors along with their official names. Click on the Fastener Tab at the top of the website and there are even more resources, including a great tutorial explaining how fasteners are identified (including how to accurately describe a bolt’s length, type, etc.)
