The Rack-A-Tiers #1 Green Square Bit | 4″ is a professional-grade driver bit designed for installing and removing #1 square (Robertson) fasteners, commonly used in electrical devices, switch plates, and precision installation applications. With a 4-inch overall length, this driver bit provides extended reach for working inside electrical boxes, cabinets, panels, and other recessed installation areas.

Part of the popular Rack-A-Tiers Racky Bits™ color-coded system, the green finish identifies the #1 square size, allowing installers to quickly select the correct bit without searching through multiple driver sizes.

Constructed with hardened steel tips, Racky Bits are designed to provide a longer service life and maintain a tight fit during repeated fastening tasks.

The standard 1/4″ hex shank fits most drills, impact drivers, and screwdrivers, making this driver bit ideal for electricians, low-voltage installers, AV technicians, and maintenance professionals performing device installation and equipment mounting.
