Hillsdale Terminal Screw-On Wire Connectors

Wire connectors are ideal for splicing multiple electrical wires together. They come in a wide variety of sizes and types. Simply strip the insulation off the ends of your wires, join them together, twist (although twisting is not necessary with free spring wire connectors), and screw your wire connectors over the wire ends.

What Are Wire Connectors For?

Wire nuts, also known as wire connectors or twist-on wire connectors, are electrical components used for joining or splicing electrical wires together. They are commonly used in electrical installations, repairs, and wiring connections in residential, commercial, and industrial settings. The primary purposes of wire nuts include:

Electrical Connections: Wire nuts are used to securely join two or more electrical wires, creating a reliable and safe electrical connection. They ensure that electrical current can flow between the connected wires without any interruptions or risk of short circuits.

Wire Splicing: When extending or repairing electrical circuits, wire nuts are used to splice (connect) wires together, enabling the electrical system to continue functioning properly

Insulation: Wire nuts also serve as insulating devices, as they typically have a plastic or rubber casing that protects the exposed wire ends, preventing accidental contact with live wires and minimizing the risk of electric shocks.

Color Coded Identification: Wire nuts often come in various colors, each denoting a specific size and capacity for wire combinations. This color-coding makes it easier for electricians and DIY enthusiasts to match the right wire nut to the corresponding wire sizes and ensures a proper and secure connection.

Reusability: In some cases, wire nuts can be reused if needed, although it's generally recommended to use new ones for safety and reliability.
