Fork terminals slide around and secure to screws or threaded connection posts to create semipermanent connections between wires and circuit points. Also known as spade lug terminals, they attach power or ground wires to post-type terminals in moderate-vibration applications such as speakers, circuit boards, and busbars. They have a barrel-shaped body, where stripped conductors insert and are either crimped or soldered to hold them, and a flat, prong-shaped terminal that connects to termination posts without removing the screw or nut altogether.
