High-quality 12 x 65mm Tek Screw into Steel (50 Pack) for fixing industrial fibreglass roofing sheets to steel structures. Requires 32mm Weatherlok Washer (sold separately) for watertight sealing and lasting performance.
The 12 x 65mm Tek Screw into Steel (50 Pack) is a reliable, heavy-duty fastener designed specifically for fixing industrial fibreglass roofing and wall sheets to steel purlins and framing. Built for strength and efficiency, these screws provide superior holding power and corrosion resistance for long-term, weatherproof installations.
Each screw features a self-drilling Tek point, allowing it to penetrate both fibreglass and steel in one easy step — no pre-drilling required. This ensures quick, clean installation and a tight mechanical bond, reducing the risk of sheet cracking or damage.
When paired with a 32mm Weatherlok Washer (sold separately), the fixing forms a watertight, vibration-resistant seal, protecting against leaks and corrosion at the fastening point. Made from high-grade, corrosion-resistant steel, these screws are ideal for industrial, rural and commercial roofing applications, offering consistent, professional results.
