Sta-Kon A480 NON-INS RECT RING TERM, 22-18, No8

The A480 is sized for 22 to 18 AWG stranded or solid copper conductor. Anything heavier than 18 AWG will not seat in the barrel, and a conductor smaller than 22 AWG won't crimp reliably, so step to the correct color-coded size range for those wires.

It is a No. 8 ring tongue, so it goes over a #8 stud or screw. On a terminal block or ground lug with a #10 screw, the ring will slip over but won't be captured properly, and on a #6 it won't pass at all.

It is a non-insulated terminal, bare copper with a metallic finish. There is no nylon or vinyl sleeve, so if the connection needs strain relief or coverage you add heat shrink or a separate insulating cap after crimping. In enclosed panels and on ground points that is often not required at all, which is why the non-insulated version gets specified.

A ring tongue like the A480 has to be unbolted to come off, so it cannot vibrate loose or pull out sideways from under a screw head. That makes it the choice for ground connections, motor terminals, and anything subject to vibration. A fork or spade terminal installs faster on a crowded terminal strip because you don't have to back the screw all the way out, but it will back off under movement. For 22-18 AWG control and signal wiring landing on #8 screws, the ring is the safer termination.

It needs a crimper matched to non-insulated terminals, not the color-coded insulated-terminal jaws. Insulated dies crimp over a sleeve this terminal doesn't have, and will deform the bare 22-18 AWG barrel instead of forming a proper indent. Use a non-insulated Sta-Kon style tool and the die position for 22-18 AWG.

It will, as long as the ground screw is a #8. The barrel takes 18 AWG copper and the copper body carries the bond without a dissimilar-metal issue at a copper or plated connection point. For a green-wire ground where the screw is #10, go to the equivalent No. 10 ring instead.

Yes, country of origin is the United States. That matters on federal, Buy American, and some institutional procurement work where domestic origin is a line item on the submittal.
