Our Hanger bolts are essential solar fasteners used to securely fasten PV mounting systems to steel purlins or rafters on corrugated, trapezoidal or fiber cement roofs. They provide a strong load-bearing connection and are ideal for windy areas. Used with L-feet or aluminum plates, they ensure stable rail mounting. Each bolt includes three flange nuts and a UV-resistant EPDM washer to prevent water leakage.
