As a crucial component used in PV mounting systems, the Steel Dowel Screw Hanger Bolt provides a secure and stable connection between the solar panel and the mounting structure. The hanger bolt is made of high-quality steel and is designed with a screw-like thread that allows for easy installation into a variety of materials such as wood, concrete, or steel. The flange nut at the end of the bolt provides additional support and stability and ensures a strong and secure connection between the solar panel and the mounting structure.
