Decking Screws for Steel Joists
Decking Screws for steel joists have a hardened self drilling point which cuts through mild steel without the need for pre-drilling. The Self Drilling Wing helps prepare the timber for countersinking, whilst the self embedding nibs help to penetrate when countersinking. The galvanised coating is suitable for most outdoor applications. The Countersunk Winged Self Drilling Screw is often used to attach fence pickets to a steel frame, or attaching merbau/treated pine to metal battens. Please be aware that due certain to environmental conditions expansion of timber can snap these screws. It is always worth consulting your timber supplier on which screws to use and use heavy gauge screws than in timber to timber applications.
