Roofing Screws are specialized self-drilling fasteners used for fixing roofing sheets and cladding panels to metal or wooden structures. They are manufactured with hardened steel, threaded bodies, and sealing washers to ensure strong holding capacity and protection against water leakage. Roofing screws are available in various diameters, lengths, and coating types as per standard specifications, and are identified by their size, thread type, and head design.
