Heavy-duty 14 X 85 Class 4 F/G Tek & 32mm W/lock Washer designed for fixing industrial fibreglass roofing sheets to steel structures. Provides superior corrosion resistance and a watertight, long-lasting seal.
The 14 X 85 Class 4 F/G Tek & 32mm W/lock Washer is a premium-grade fastener system designed for fixing industrial fibreglass roofing and wall sheets to steel purlins and frames. Built for performance and durability, this screw and washer combination delivers a strong, watertight connection ideal for demanding outdoor and industrial environments.
The Class 4 galvanised coating provides outstanding corrosion resistance, making it suitable for coastal and high-moisture areas where long-term durability is essential. The self-drilling Tek point eliminates the need for pre-drilling, ensuring fast, efficient installation through both fibreglass sheets and steel supports.
Paired with a 32mm Weatherlok bonded washer, this system ensures a tight, weather-sealed joint, protecting against leaks and vibration. The washer’s wide diameter distributes pressure evenly across the sheet surface, preventing cracking and prolonging sheet life.
Ideal for industrial roofing, agricultural buildings, factories, and sheds, these fixings are engineered for strength, ease of use and long-term performance in harsh Australian conditions.
