Product Overview
Hexagon flange head self-drilling screw, also commonly referred to as a self-drilling screw, is a multifunctional fastener specifically designed for the rapid fastening of metal components. It integrates the three processes of drilling, tapping, and fastening into one unit, eliminating the need for pre-drilled holes and allowing direct one-step installation on substrates such as steel sheets and color steel tiles, significantly improving construction efficiency. This screw is made of a carbon steel substrate with a mechanical zinc plating Grade 3 surface treatment, balancing strength, corrosion resistance, and cost-effectiveness. It is one of the most widely used fasteners in light steel structures, roofing enclosures, and other engineering applications.
Product Applications
