Key Benefits of Waterproof Metal Screws 1. Superior Waterproofing The integrated EPDM washer creates a tight seal around the screw penetration point. EPDM rubber is highly resistant to UV rays, ozone, extreme temperatures, and moisture. This ensures that water cannot seep through the screw holes, reducing the risk of leaks, mold, and structural damage. 2. Corrosion Resistance for Longevity Outdoor screws are exposed to rain, snow, and humidity, which can cause rust over time. The painted or coated heads of waterproof screws provide an additional layer of protection, keeping the metal intact and extending the lifespan of the fasteners. Unlike standard screws, these high-quality fasteners maintain their structural integrity even in harsh environments. 3. Efficient Installation and Strong Holding Power Many waterproof screws from Zhejiang Jiaxing Tuyue feature self-drilling tips, eliminating the need for pre-drilling holes and reducing labor time. The precision-cut threads ensure a secure grip on both metal and wood substrates, preventing loosening due to wind, thermal expansion, or structural movement. This combination of ease of installation and durability makes them ideal for both new constructions and roof retrofits. https://www.global-tuyue.com/roofing-screw-with-epdm-washer-painted-head.html Common Installation Mistakes to Avoid Even high-quality screws require proper installation. Over-tightening can crush the EPDM washer and compromise the seal, while under-tightening may allow water infiltration. Screws installed at an incorrect angle or with the wrong length can also reduce performance. Regular inspection ensures that the waterproof seal remains intact and that the screws continue to provide maximum protection. Ideal Applications Residential and Commercial Roofing: Homes, offices, warehouses, and other metal structures benefit from leak-resistant fasteners. Industrial and Agricultural Buildings: Barns, factories, and warehouses require long-lasting, low-maintenance solutions. Harsh Weather Conditions: Waterproof screws perform well in regions with heavy rain, snow, or extreme UV exposure. Repairs and Retrofits: Upgrading old nails or standard screws to waterproof screws can dramatically improve roof longevity and reliability.
