Taptite screws are thread-forming fasteners designed to create their own threads in untapped holes, especially in metals and plastics. Featuring a trilobular shape and tapered tip, they reduce driving torque, improve thread engagement, and resist loosening under vibration. Commonly used in automotive, electronics, and appliance assemblies, Taptite screws enable fast, reliable, and cost-effective assembly without the need for pre-tapped holes.
