Self-drilling screws are mainly used for fast connection between metal components in photovoltaic systems, especially suitable for fixing and installing thin steel plates and section steel structures.
With a self-drilling tail design, they can drill directly into metal substrates and eliminate the need for pre-drilling holes.
Made of carbon steel with galvanized surface treatment, self-drilling screws offer excellent corrosion resistance. Featuring high installation efficiency and firm connection performance, they are widely applied in rooftop and carport photovoltaic projects, serving as common fasteners to improve construction efficiency and ensure connection reliability.
