Hex Head Self-Drilling Screws for Metal Roofing are specially engineered for fast, secure, and weather-resistant fastening of metal roofing sheets to steel or wood structures. The precision self-drilling point eliminates pre-drilling, while the hex washer head delivers high torque transfer and stable installation. These screws are widely used in industrial buildings, warehouses, agricultural sheds, and commercial roofing systems.
