3M 7100164150 – Frequently Asked Questions
1) What wire size does the 3M Scotchlok M8-38RK ring terminal take?
It is a single-gauge terminal built for 8 AWG conductor only, with both the minimum and maximum conductor size listed at 8 AWG (8.37 mm2). Do not try to crimp 10 or 6 AWG in it; the barrel is sized for one gauge and a loose or over-stuffed crimp will not hold pull-out.
2) Will this ring terminal fit a 3/8 inch stud on a panel lug or ground bar?
Yes. The M8-38RK ring tongue is made for a 3/8 inch stud, with a connection width of 0.375 in (9.525 mm). The ring slips over the stud and the nut clamps it down, so it stays put if the nut is backed off, unlike a spade or fork terminal.
3) Is the 3M M8-38RK ring tongue insulated?
No, it is a bare non-insulated brazed seam terminal. Bare metal means you supply your own insulation at the barrel, typically heat shrink or tape, wherever the connection needs to be covered. If you want the insulation built in, choose a nylon or vinyl insulated ring terminal for 8 AWG instead.
4) How much room do I need in the enclosure for this 8 AWG ring terminal?
The terminal measures 1.06 in overall length by 0.59 in overall width, so it is compact enough for crowded panel gutters and ground bars, but check tongue clearance where studs sit close together.
5) What voltage and temperature can the Scotchlok M8-38RK handle?
Rated 600V for building wire and 1000V for signs, fixtures or luminaires, with a service temperature range of -40 to 221 degrees F (-40 to 105 degrees C). That covers most commercial lighting and sign work as well as standard branch circuit terminations.
6) Will these ring terminals corrode in a damp or outdoor sign enclosure?
The terminal body is electrolytic copper with tin plating for corrosion resistance, which is what you want in damp locations and sign cans. Since the barrel is bare, seal it with adhesive-lined heat shrink if it will see standing moisture.
7) How many 3M M8-38RK ring terminals come in a case?
They are packed 200 per case under 3M part number 7100164150, which is the quantity to plan on for a panel changeout or a lighting retrofit where you are landing a lot of 8 AWG.
8) Where are 3M Scotchlok ring tongue terminals made?
Country of origin is the United States, which matters on public works and government jobs carrying domestic sourcing requirements.
