Solar Self-Tapping Hanger Bolt (with Self-Tapping) is a fastener specifically designed for the installation of solar photovoltaic systems on steel structures, combining the features of a hanger bolt and a self-tapping screw. It consists of a bolt with threads on both ends—one end has external threads (for fastening to the steel structure or support frame), and the other end has internal threads (for connecting other components). Unlike traditional bolts, this bolt has a self-tapping feature, which allows it to create threads directly in the metal material during installation, eliminating the need for pre-drilling and simplifying the installation process.
A self-tapping hanger bolt is a fastener that combines the characteristics of a hanger bolt and a self-tapping screw. One end features external threads (for securing to steel structures), and the other end features internal threads (for connecting to other components). The self-tapping function means that the bolt can cut internal threads directly into the metal surface during installation, avoiding the need for pre-drilled holes.
Self-Tapping Design: The tip of the bolt is designed with self-tapping threads, allowing it to cut into the metal material directly during installation, eliminating the need for pre-drilling and simplifying the process.
High-Strength Materials: Typically made from high-strength steel, stainless steel, or alloy materials, providing excellent corrosion resistance and durability, suitable for long-term outdoor exposure in solar power systems.
Corrosion Protection: The bolts are often galvanized or treated with other corrosion-resistant coatings to enhance their durability in harsh environments.
Dual-Thread Design: One end features external threads (for fastening to the steel structure), while the other end has internal threads (for connecting photovoltaic mounting brackets, panels, and other components), making it versatile for various installation needs.
Ease of Installation: The self-tapping feature simplifies installation, eliminating the need for extra tools or time-consuming pre-drilling, significantly increasing construction efficiency.
Strong Adaptability: Suitable for various metal thicknesses and types, providing reliable fixation and connection for different installation environments.
