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.
