These 5" (125mm) pliers have a unique compound joint to keep the 30x6x2mm flat jaws parallel to each other as they open and close, providing an even pressure across the entire working area. Ideal for flattening wire loops and spirals, crimping sheet metal, forming smooth curves in wire and metal, and truing bent components. Because the jaws stay together in a semi-locked position, they're also useful for holding objects, wires, or pieces of metal sheet for easier working. Curved, textured handles and sturdy construction help with even the toughest metal projects.
