The Ultimate Waterproof Fastening Solution.
Umbrella Head nails with integrated washers or caps are specialized fasteners designed to create a watertight seal around the nail shaft. Featuring a large, domed plastic head and an EPDM or plastic washer, they are engineered to prevent water infiltration in roofing and cladding applications, making them essential for weatherproof installations.
Integrated Washer/Cap Design: A large, durable plastic cap is permanently fused with a waterproof EPDM or neoprene washer, forming a single, reliable unit.
Wide Sealing Surface: The broad diameter of the cap and washer distributes pressure evenly and creates a large sealing area to block water entry.
Watertight Compression Seal: When driven, the washer compresses tightly against the material surface, forming a permanent, waterproof barrier around the nail shank.
Corrosion-Resistant Shank: The nail is typically made of galvanized steel or stainless steel to prevent rust from compromising the seal.
UV-Stabilized Plastic Cap: The umbrella head is resistant to weathering and solar degradation, maintaining its integrity and color over time.
