Blue flanged fork terminals are for 16-14 AWG wire. Flanged fork terminals are very popular electrical connectors. They are built for easy attachment and removal from connections such as bus bars. What separates them from other terminals such as locking fork terminals? Locking forks "snap" around the screw. Flanged forks have the tips of the forks bent up. This allows it to "grab" the screw or bolt that they are being connected to. Due to their ease of use and narrow size, they are used with terminal blocks quite often. These high quality terminals are currently available in nylon insulation. Easy to use and built to last.
