3M™ Scotchlok™ Locking Fork is a lug connection terminal that has a spring-like tongue to securely lock around the stud. The non-insulated, brazed-seam barrel has a beveled mouth that guides the wire into position, and it withstands a maximum temperature of 347 degrees F (175 degrees C). Electrolytic copper construction offers good conductivity and a tin-plated finish resists corrosion.
