6.3 x 110mm Fibre Cement Baz Tekscrews for Light Section Steel

Secure Fibre Cement Sheets with Confidence When installing fibre cement roofing and cladding sheets, achieving a secure, weather-resistant fixing is essential for long-term performance. These 6.3 x 110mm Fibre Cement Screws are specifically designed to fasten fibre cement sheets to light section steel purlins, providing strong, reliable fixing performance in demanding construction, agricultural and industrial environments. Manufactured from carbon steel and protected by an advanced 500+ corrosion-resistant coating, these specialist fasteners are engineered to deliver consistent installation performance and long-term durability. Complete with sealing washers and a self-drilling point, they help simplify installation while providing a secure and watertight connection. Designed for Fibre Cement Roofing Systems Purpose built for fibre cement applications, these screws are suitable for fixing fibre cement sheets to cold rolled steel purlins ranging from 1.2mm to 3.0mm thick. The integrated reamer on the shank creates additional clearance within the sheet, helping accommodate natural expansion and contraction caused by temperature changes. This helps reduce stress around the fixing point and supports the long term integrity of the roofing system. Strong Fixing Performance and Weather Protection The high-clamping design provides excellent holding power, helping secure fibre cement profiles firmly in place. Supplied with sealing washers as standard, these fixings help create a watertight seal around the fixing point to minimise the risk of water ingress. For enhanced durability, the screws feature an advanced 500+ corrosion-resistant coating engineered to withstand over 500 hours in neutral salt spray testing. The multi-layer coating system combines sacrificial zinc protection, chemical passivation and a ceramic surface layer to provide outstanding resistance against rust, abrasion and environmental exposure. This protective finish helps extend service life in demanding external applications while maintaining the drilling performance and installation characteristics required for fibre cement fixing systems. Fast and Efficient Installation Featuring a self-drilling gash point, the screw is designed to drill efficiently through light section steel while helping clear swarf from the hole during installation. The hex head design allows for quick installation using a standard 5/16" socket, offering compatibility with commonly used roofing and cladding installation tools. Combined with the durable carbon steel construction, these screws deliver the performance and reliability required for professional roofing projects.
