3M™ Scotchlok™ Ring Tongue Terminal ensures an ideal fit while offering reliable and safe performance. The terminal has a vinyl-insulated, brazed-seam barrel that can withstand temperatures of -40 to 221 degrees Fahrenheit (-40 to 105 degrees Celsius). The electrolytic copper construction offers good conductivity and a tin-plated finish resists corrosion. Its ring shape is the safest and most reliable, because it cannot be removed unless mounting screw is removed. 3M™ Scotchlok™ Ring Tongue Terminals are colour-coded for quick and easy identification of the wire size required.
