Hex Nuts: Also known as finished full, these nuts are used for fastening to a bolt while joining materials together mechanically.	Hex machine screw nuts: These nuts are used with smaller machine screw sizes under ¼ inch, and are used to fasten a bolt mechanically.
Coupling nuts: These nuts are long nuts to connect pieces of male threaded fasteners or threaded rods.
