Sta-Kon D73U NON-INS RING 8AWG 3/8BH 90DEG BEND

The D73U is sized for 8 AWG conductor. One wire size only, so if you are terminating 10 AWG or 6 AWG on the same panel you need a different barrel size. The barrel is copper, crimped rather than soldered.

The tongue on the D73U sits at a right angle to the wire barrel, so the conductor runs parallel to the mounting surface and the ring lands flat on a stud facing out. That is what you want when the stud is on the side of a bus bar, a motor terminal block, or a tight enclosure wall where a straight terminal would force a sharp bend in the 8 AWG wire. If your stud faces the same direction the wire runs, use a straight (flag-free) ring terminal instead.

It is non-insulated bare copper. Nothing covers the barrel, so if the terminal sits where it could contact a grounded surface or an adjacent phase you need to sleeve it yourself with heat shrink or tape, or pick an insulated ring instead. On the plus side, a bare barrel takes a two-stage or hex crimp and lets you see conductor fill before you crimp.

A color-coded insulated-terminal crimper will not do this one. Non-insulated copper barrels in 8 AWG want a non-insulated die set, typically a hex or indent crimp rated for that barrel size. A plier-style insulated tool will deform the barrel without making a full compression on the conductor.

Yes, country of origin on the D73U ring terminal is the United States. That matters on federal, state and institutional jobs carrying Buy American or domestic-preference language in the spec.

Order it as Sta-Kon D73U. That designation covers the non-insulated 8 AWG ring with the 3/8 inch bolt hole and the 90 degree bend, and there is a single model on it, so no finish or size suffix to pick.
