Sta-Kon A18-8F NON-INS FORK TERM 22-16 No8

The A18-8F takes 22 to 16 AWG stranded copper wire. That's the full range for this one barrel size, so 14 AWG and larger won't seat in it, and anything finer than 22 AWG won't get a reliable crimp. If your conductor is 14 or 12 AWG you need the next barrel size up in the Sta-Kon fork line.

It's a No. 8 stud fork terminal, so it slips over a #8 screw or stud, typical of terminal blocks, control panel strips, and device terminals. Because it's a fork (spade) rather than a ring, you can slide it under a loosened screw without removing the screw entirely, which is why they get used on crowded terminal strips where backing a screw all the way out means losing it.

It's a non-insulated terminal, bare copper with no nylon or vinyl sleeve. In a crowded enclosure that means you get no strain relief or spacing from the terminal itself, so either keep clearance to adjacent terminals or sleeve the barrel with heat shrink after crimping. The upside is a lower profile and the ability to inspect the crimp, which some inspection regimes prefer.

600 V, which covers standard commercial and industrial control wiring, lighting circuits, and 480 V three phase panel work. It carries UL file E9809.

Use a ring. A fork terminal like the A18-8F is open on one end, so if the screw backs off under vibration the conductor can walk out of the terminal entirely. Fork terminals are the right call where you're servicing terminal strips often and want to pull a wire without removing hardware. On motors, compressors, rooftop units, and anything that shakes, a ring terminal in the same 22-16 AWG range is the safer termination.

No. It's a copper terminal and should be crimped to copper conductors only. Aluminum branch wiring needs a terminal rated AL/CU for that purpose, otherwise you get galvanic corrosion and a joint that loosens over time.

Country of origin on the A18-8F is the United States, which is the documentation most federal, municipal, and school district procurement offices ask for on electrical consumables.

Manufacturer part number A18-8F. The designation reads out as the Sta-Kon A series, 18 for the 22-16 AWG barrel, 8 for the No. 8 stud, and F for fork tongue. If you need a different stud size with the same wire range, the barrel digit stays and the stud digit changes.
