Timco 6.3x130mm BAZ Washer Screws for Fibre Cement Boards, 50 Pieces

The Timco BAZ Washer Screws are specifically designed for securing fibre cement profile sheets to timber. These screws feature a heavy-duty EPDM and stainless steel washer, ensuring a water-tight seal to protect against leaks and corrosion. The exterior silver organic coating provides exceptional corrosion resistance, withstanding over 500 hours of salt spray testing, making them ideal for harsh outdoor environments.

These screws are particularly well-suited for securing Big 6 roofing sheets and are equipped with wings that ream an enlarged hole in the roofing sheet to accommodate expansion, reducing the risk of sheet damage over time. The combination of hex head, slash point, and fixed washer ensures easy installation and robust fastening.
