First introduced in 1928, IDEAL Wire-Nut wire connectors set the bar for quality and convenience. A fixed, square-cut spring, and a tough, flame-retardant shell, provide a secure connection that lasts. Twisting by hand is a breeze thanks to the positive grip design that is also compatible with IDEAL Twist-a-Nut screwdrivers for additional ease and speed. Its wide wire range is suitable for a variety of applications and is an ideal choice when working with fine stranded wire. The original Wire-Nut, still an industry standard today.
