With these Spax decking screws, you can fasten timber deck boards securely and tightly to the substructure. The fixing thread locks the boards firmly in place, eliminating annoying creaks and squeaks underfoot. Thanks to the cut drill point, timber splitting is minimised during driving, allowing you to work quickly and efficiently. The slim cylindrical head sinks flush and discreetly into the wood for a clean, professional terrace finish. The t-star plus T25 drive delivers positive engagement without bit slippage, while the A2 stainless steel construction provides reliable, long-lasting corrosion resistance for outdoor projects.
