These electrical wire connector nuts allow for simple and efficient connections of multiple wires with varying sizes. CableTiesAndMore now carries two varieties of wire connectors, non-winged fixed spring and winged free spring. To use, simply remove the insulation from the wires near the connection end. Next, twist the wires together, though this isn't required if you're using the winged, free spring connectors. Then screw on the connector over the ends of the exposed wires. We provide an array of different sized connectors to meet your wiring needs. Our products are color-coded to aid in identifying the gauge of wire that it will effectively accept.

cone shaped, plated steel spring conforms to the inside contour of the insulating shell, which supports the spring as the conductor is driven up into the cone. Requiring no pre-twisting, the wires are automatically twisted together for a secure connection and maximum contact. Fixed spring wire connectors may be used to make branch circuit or fixture wire connections on numerous combinations of solid and/or stranded wire.

square wire, coiled spring expands freely within the tough plastic shell and can accommodate a wide range of wire combinations. The angled edges of the spring attaches to the conductor as the connector is twisted on for an easily secured joint. The spring applies even pressure over the entire contact area, and provides a low resistance connection and mechanical strength against pull and vibration.
