Techfast Roofing Screw Timber To Steel Heavy Section 5.5 x 60mm Pack 100

The Forgefix TechFast Roofing Screws are designed for joining timber to heavy gauge steel sections, providing a reliable fastener for roofing and construction applications. Each pack contains 100 screws with a 5.5 x 60 mm size and a countersunk head that sits flush on the surface. The screws feature a self-drilling point to enable quick insertion and a winged design that creates a clearance hole in the timber, reducing the risk of jacking during installation. The coating, known as Elementech, offers corrosion resistance and has been tested for salt spray exposure, enhancing durability in harsh environments. These heavy-section screws are suitable for timber-to-steel fixing where steel thickness ranges from 6.0 mm to 12.5 mm, with a maximum fixing length of 25 mm. A Torx TX compatible bit is included, ensuring efficient power transmission and easy installation. In addition to timber and heavy steel purlins, these screws are intended for use in joining timber to steel frame components, including heavy section purlins, with breakaway wings designed to ream a hole and then break off when contacting the metal surface to protect threads in timber during drilling.
