3M™ Scotchlok™ Ring Tongue Terminal ensures an ideal fit while offering reliable and safe performance. The terminal has a vinyl-insulated, brazed-seam barrel and withstands temperatures of -40 to 221 degrees Fahrenheit (-40 to 105 degrees Celsius). Its electrolytic copper construction offers good conductivity and a tin-plated finish resists corrosion. The ring is the safest and most reliable style of tongue as 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.
