Professional Applications & Engineering Value
These Black Oxide Steel tapping screws solve critical fastening challenges in steel and sheet metal applications where vibration resistance and permanent installation are paramount. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time while creating stronger threads that won't loosen under stress. The No. 2 drill tip efficiently penetrates up to 0.1" material thickness, making them ideal for HVAC systems, electrical enclosures, and metal fabrication where precise, secure fastening is essential. The oval head design with 82° countersink provides a flush finish that enhances both aesthetics and safety in visible applications, while the Phillips drive system ensures reliable installation without specialized tools.
Specification Summary & Compliance
