The Wolfcraft 6174000 Crimping Jaws are a set of high-grade, durable splicing jaws for creating zip ties, cable wire, and other material connections. The set can be used on WIREFLY cables and wires, Wolfcraft’s WF6177000, WF6182000, and WF6906000 wires, as well as many other models. They are designed to create secure and reliable connections and withstand heavy use. The crimp and cut areas on the jaws are made from hardened and tempered steel, while the plastic covers and knurling provide good ergonomic and tactile feedback. The self-adjusting design ensures an even compression and a consistent finish.
