Sta-Kon C480SP NONINS RET TONGUE 12-10 No8 SLVRPLT

The C480SP is sized for 12 to 10 AWG conductor. Crimping it onto smaller wire like 14 or 16 AWG will leave the barrel loose and the connection unreliable, so step down to a terminal rated for that range instead.

It is built for a No. 8 stud or screw. That matches typical #8 terminal block and equipment lug studs, so check the stud diameter on your breaker, motor terminal, or ground bar before ordering.

It is a non-insulated terminal, so the crimp barrel is bare metal. If the termination sits where it could contact an adjacent conductor or a grounded surface, plan on heat shrink or an insulating sleeve over the barrel. In an enclosed terminal block or inside a lug cover, bare is normally fine.

The body is copper with a silver-plated finish, which is why it reads silver in color. Copper barrel means it is intended for copper conductor, not aluminum. Silver plating keeps contact resistance low and is common where the connection carries higher current or sees heat.

Both are closed-ring terminations that go over a stud and get locked down with a nut. The rectangular tongue on the C480SP gives a flat, squared pad rather than a round one, which seats better on narrow terminal blocks and bus pads where a round tongue would overhang or rotate. If you have open space around the stud and just need a secure closed connection, either works; where the landing pad is slotted or tight, the rectangular tongue is the one to use. A spade or fork terminal would be the alternative if you need to pull the wire off without removing the nut, but it does not stay captive like a ring does.

No. Non-insulated copper barrels of this type need a die-set crimp tool matched to the 12-10 AWG range, not the plastic-handled strip-and-crimp pliers used on insulated vinyl terminals. An uncalibrated squeeze on a bare barrel gives you a connection that passes a tug test and fails under vibration or load.

Yes, country of origin is the United States. That matters on government, school district, and other publicly funded jobs carrying domestic-sourcing requirements for electrical materials.

Order Sta-Kon C480SP. That is the manufacturer part number for the non-insulated silver-plated rectangular ring tongue terminal, 12-10 AWG, No. 8 stud.
