Screw-On Wire Connectors

Screw-on wire connectors (wire nuts, twist-on connectors) provide fast, reusable connections for joining multiple solid or stranded copper wires in residential, commercial, and automotive electrical applications without crimping tools. These UL 486C listed and CSA certified twist-on caps accommodate wire combinations from 22-14GA up to 22-8GA, using internal threading and spring clips to mechanically secure wires while maintaining electrical contact.
