3M 512 Electrical Spring Connector Wire Nuts Assortment

The 3M 512 Electrical Spring Connector Wire Nuts Assortment is a bulk bag containing 500 3M 512 spring-type wire connectors. They are designed to join copper conductors in the #18 to #12 AWG range, making the set suitable for small-diameter residential and light commercial wiring splices. This assortment is intended for use in electrical boxes, junction boxes, panels, or conduit runs where compact, space-saving connectors are preferred. The 3M 512 family uses a spring mechanism to grip conductors securely, providing a reliable termination for copper wires within the specified gauge range. Packaging as a 500-piece bag supports higher-volume projects or ongoing maintenance, reducing the need for frequent restocking of wire connectors.
