Sta-Kon RB1347M VIN INS RING TERM 18-14 No8 MYLAR

It's a No. 8 ring, so it lands on a #8 screw or stud. Typical spots are terminal blocks, ground screws, motor terminal boards, and panel lugs prepped for #8 hardware. A #10 stud will not pass through the tongue.

Ring, not fork. The closed tongue means the connection can't back off the stud if the screw loosens, which is why most equipment ground connections and vibration-prone terminations get specified as rings. A fork (spade) terminal slips off under a loosened screw but lets you land it without fully removing the hardware. For panel work where the screw comes all the way out anyway, use the ring.

Vinyl insulation over the barrel, with a Mylar-lined sleeve. Vinyl insulated terminals are the standard choice for general panel, control, and appliance wiring at ordinary temperatures; if you're terminating inside a high-heat enclosure or near a motor housing that runs hot, spec a nylon-insulated or heat-shrink terminal instead.

Use an insulated-terminal crimp tool matched to the 18-14 AWG range, commonly the blue die position on a color-coded crimper. Pliers or a bare-terminal die will crush the vinyl sleeve and leave a connection that pulls out. No tool is included with the terminal.

Yes, as long as the ground screw is a #8 and the conductor falls in the 18-14 AWG range. The ring tongue is the form most grounding terminations call for because it stays captive on the screw. For a 12 AWG equipment ground, which is common on 20 amp branch circuits, you'd need a larger terminal.

Manufactured in the United States. That matters on federal, state, and institutional jobs carrying domestic sourcing language, where a foreign-made terminal gets rejected at submittal.

Order by manufacturer part number RB1347M from Sta-Kon. There's one configuration, so there's no finish, length, or stud-size option to specify. The number itself encodes the 18-14 AWG barrel and the #8 ring.
