Hex Head Fine Thread – c/w Bonded Washer

Hex Head Fine Thread Tek Screws with bonded washers are purpose-built for fastening profiled metal roofing and cladding sheets into hot-rolled steel between 5.0mm and 12.5mm thick. These high-performance fixings feature a fine thread profile for optimal grip in steel substrates, making them especially suitable for structural and industrial applications where strength and precision are critical. The integrated bonded washer enhances the overall performance of the fixing by providing a durable, weather-resistant seal that helps prevent water ingress and protects against corrosion. It also distributes the load more evenly across the sheet surface, reducing the risk of material damage or pull-through over time. These screws are ideal for use in exposed environments where reliability and sealing integrity are essential. With a hexagonal head designed for rapid installation using power tools, they offer excellent efficiency on-site while maintaining strong and secure fixings in demanding conditions.
