Sta-Kon C223-TB UNINS LKG FRK TRM 12-10 BLT 1/4 IN

The Sta-Kon C223-TB locking fork terminal is sized for 12-10 AWG stranded wire. If you are terminating 16-14 AWG or 8 AWG conductors, you need a different barrel size, since crimping outside the rated range gives you a connection that can pull out or heat up under load.

A ring terminal is the more secure choice because it cannot come off unless the nut is removed, and many specs require rings on power connections. A 1/4 inch locking fork like the C223-TB is the choice when you need to service the connection fast or cannot fully back out the screw, as on a crowded terminal strip, and the locking tangs recover much of the retention a plain spade gives up.

It is a non-insulated terminal, bare metal barrel and tongue. In tight panels or anywhere adjacent terminals are close together, you either add heat shrink or sleeving after crimping, or specify a nylon or vinyl insulated fork terminal instead. Non-insulated is also what you want when the lug sits under a terminal block cover or where the crimp needs to be inspected.

The locking fork has upturned or formed tangs at the tips of the tongue, so once the screw is torqued down the terminal resists sliding back off the stud under vibration. That is the difference between this and a plain spade terminal, and it is why locking forks get used on motor controls and vibrating equipment where a standard spade can walk out.

Country of origin is the United States, which is what institutional and government buyers working to domestic-content purchasing rules will want on file for this terminal.

Non-insulated terminals crimp with a non-insulated (open barrel or nest-and-indenter) die, not the color-coded insulated die set. Match the die to the 12-10 AWG range. Terminals, dies, and insulating sleeving are ordered separately from the lug itself.
