100PK Spring-loaded Wire Nut Connector: 14-8 AWG, Gray, Gardner Bender GB8-14, EE3

The Gardner Bender (GB) Gray Hex-Lok wire connector (often in the 14-8 AWG range) is a professional-grade, twist-on connector designed for connecting multiple copper wires. Featuring a durable, flame-retardant thermoplastic shell, these gray connectors use a square-wire spring to create a secure connection. The unique hex-head design allows for easy installation by hand or with a 7/16" socket driver, while the long, deep skirt helps prevent exposure of bare wire, offering superior flash-over protection. They are rated for 600V maximum in building wire and 1000V in lighting/signs, making them suitable for large appliances, switches, and commercial applications.
