Premium Material: These electric connectors for wiring are made from thermoplastic engineering plastic molded shell, which is thick and has high hardness that not easy aging. Flame retardant wire nut cap fire rating up to UL94V-2.
Strong Spring: The spring of the wire nut is made of galvanized carbon steel material, greatly ensuring the connection stable and preventing the electric wire from falling off. The metal spring of electrical wire connectors provide strong wiring and good conductivity!
Safety and Insulating : Our electrical wire caps can grab the wires firmly, and effectively avoid unstable wire connection, enhancing the safety and insulation.
Easy and Quick to Use: The wirenuts are perfect to connect wries without soldering, just insert the stripped conductors into the wire cap, then screw the terminal into the wire.
