4.5mm Decking Screws

Our High-Performance Decking Screws are engineered to withstand the rigours of outdoor use. Specifically designed for external timber projects, these screws feature a specialised weather-resistant coating that prevents rusting and bleeding into the wood. The sharp point and unique thread design allow for fast insertion with minimal risk of splitting the timber, while the ribs under the head ensure the screw countersinks itself perfectly for a smooth, trip-free surface. Whether you are a professional landscaper or a DIY enthusiast, these screws provide the grip and longevity required to keep your decking boards securely fastened to the joists, even as the timber naturally moves over time. Weather Resistant: Coated to provide excellent protection against the elements, ensuring your deck remains secure for years to come. Self-Countersinking: Specially designed heads sit flush with the timber surface without the need for pre-drilling in most softwoods. High Pull-Out Resistance: Deep threads ensure a powerful grip into the timber joists, preventing boards from “popping” or creaking. Versatile Packaging: Available in smaller boxes for repairs and finishing touches, or high-value bulk tubs for full-scale installations.
