Sta-Kon A18-4 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon A18-4 ring terminal crimp onto?
The A18-4 is sized for 22 to 16 AWG stranded or solid conductor. Anything larger, like 14 or 12 AWG, won't seat in the barrel and will give you a loose crimp, so step up to a terminal rated for that range instead.
2) What stud or screw size does the A18-4 ring fit?
The ring is a No. 4 size, so it drops over a #4 screw or stud. For larger terminal screws on a breaker lug or ground bar you want a bigger ring size, not this one.
3) Is this ring terminal insulated, and does that matter in a crowded panel?
It's a non-insulated copper terminal, bare metal right up to the crimp. In a tight control panel or junction box where barrels can touch each other or a grounded surface, you'll need to add heat shrink or sleeving, or choose an insulated (nylon or vinyl) ring terminal instead.
4) Is the A18-4 ring terminal copper or aluminum, and can I use it on aluminum conductors?
The body is copper, so it's intended for copper conductors. Aluminum wire needs a terminal marked AL or AL9CU with the proper inhibitor compound; don't crimp aluminum into a copper-only lug.
5) Ring terminal or fork terminal for a 22-16 AWG control wire?
A ring like the A18-4 has to come off the screw entirely to be removed, which is why it's the choice where vibration or an accidental pull could back a wire out, and what most equipment specs call for on grounds. A fork or spade slides out from under a loosened screw, which is faster for panel service but can walk off under vibration. Same 22-16 AWG wire range either way.
6) Is the Sta-Kon A18-4 made in the USA?
Yes, country of origin is the United States, which matters if you're buying against a Buy American or domestic-preference clause on government or institutional work.
7) Do I need a special crimper for Sta-Kon non-insulated ring terminals?
Non-insulated barrels crimp with the bare-terminal die set, not the color-coded insulated nest. Using an insulated-terminal die on a bare barrel like the A18-4 gives an under-formed crimp that can pull out. Match the tool to a 22-16 AWG non-insulated terminal.
