METAL TEKSCREW 1 1/2 (BOX)

Metal tek screw, also known as a self-drilling screw, is a type of fastener with a drill bit-shaped tip that drills its own pilot hole through metal or other materials without the need for pre-drilling. This feature allows for faster installation and is used in various applications, including roofing, electrical work, construction, and HVAC, primarily for joining metal-to-metal or metal-to-wood connections.
