Weather-Sealing Self-Drilling Screws

TAS Zinc Plated Self-Drilling Screws with Sealing Washer (#8 Diameter - Taiwan)

Ensure a secure and weatherproof seal for your exterior fastening projects with TAS #8 Self-Drilling Screws, complete with pre-assembled sealing washers. Manufactured in Taiwan, these high-quality, zinc-plated screws are designed to drill, tap, and seal in a single efficient operation, making them ideal for roofing, cladding, and other outdoor construction applications. Each screw is conveniently packaged in boxes of 1000 pieces.

TAS Self-Drilling Screws with Washers are typically crafted from hardened carbon steel for reliable strength, featuring a sharp drill point for quick and easy penetration into light to medium gauge metal. The pre-assembled washer, commonly a durable EPDM or neoprene washer bonded to a steel backing, compresses during installation to create a long-lasting, watertight seal, protecting against leaks and environmental factors. The zinc plating provides good corrosion resistance. These #8 diameter screws are available in a range of lengths to suit various material thicknesses: 1/2 inch, 5/8 inch, 3/4 inch, 1 inch, and 1.25 inches. A Hex Washer Head is common for these screws, allowing for easy and secure driving.
