3M™ Scotchlok™ Fork is a lug connection terminal that has a wider tongue for use on free-standing studs. Ideal for the rapid connection of wire, these nylon insulated forks are designed to withstand temperatures of -40 to 221 degrees Fahrenheit (-40 to 105 degrees Celsius). Their wider tongues make them ideal for use on free-standing studs. Its butted-seam barrel is covered by a funnel-designed, seamless brass sleeve to help guide the wire into position, while providing electrical contacts and mechanical stress relief at the point of insulation. The abrasion-resistant, flared, nylon-sleeve insulation ensures positive grip, and has a stepped design for mistake-proof crimping. Their electrolytic copper construction offers good conductivity, while their tin-plated finish resists corrosion. 3M™ Scotchlok™ Forks are UL Recognized and CSA certified.
