Self Drilling Tek Screws Sheet to Timber c/w 16mm Bonded Washer

These self-drilling Tek screws are designed specifically for fastening metal sheets to timber. Each screw features a sharp drilling tip, allowing it to penetrate both the metal sheet and the timber substrate without the need for pre-drilling, making installation faster and more efficient. The screws come with a 16mm bonded washer, which ensures a watertight seal and distributes pressure evenly to prevent damage to the sheet. The washer is typically made from a combination of metal and rubber for durability and flexibility, helping to secure the material tightly while protecting against weather elements, corrosion, and vibrations.

These screws are ideal for roofing, cladding, and various outdoor projects where durability, weather resistance, and secure fastening are essential.
