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.
