The Giffex Screw-On Wire Connector Series provides safe, code-compliant, and secure electrical connections for residential, commercial, and industrial electrical projects. Built with a tough, thermoplastic shell and an internal fixed square-wire spring, these connector nuts bite into copper conductors upon twisting to deliver low electrical resistance and maximum pull-out protection against vibration.

All variants in the lineup are rated for continuous operation at temperatures up to 105°C (221°F) with voltage ratings up to 300V/600V MAX. Color-coded by model size for instant identification, they are sold in convenient 100-piece bags.
