These 4.8mm x 63mm composite decking screws are manufactured from non-corrosive stainless steel for long-term durability. Each pack contains 200 individual fixings designed to provide a neat, flush finish on both composite boards and pressure-treated timber. The heads are specifically coated to match common board colours, ensuring the hardware remains discreet once installed. This makes them an ideal choice for homeowners and contractors who require a secure, professional finish that resists the elements.
These fixings are suitable for a wide range of applications across the UK, from domestic garden patios in the South West to high-traffic commercial walkways in northern cities. They perform exceptionally well in damp environments where moisture levels are consistently high. Whether you are constructing a timber ramp for accessibility or laying a large composite deck around a swimming pool, these screws provide stability. They are built to withstand heavy autumn rain and the typical freeze-thaw cycles found in British winters, ensuring your outdoor flooring remains secure throughout the year.
Installation is straightforward using the included TX driver bit. The unique triple-thread design is engineered to manage debris effectively during the driving process. As you sink the screw, the second thread draws swarf downwards into the joist. This allows the board to sit perfectly flush against the substrate without any lifting. You should drive the screw until the mushroom head sits just beneath the surface of the board. This specific depth seals the composite material and prevents water ingress.
Each pack includes 200 stainless steel screws measuring 4.8mm in diameter and 63mm in length. The triple-thread architecture features a first thread for joist grip, a second for swarf management, and a third to secure the board. A coated mushroom head prevents splitting while sitting flush beneath the surface. Every pack comes with a compatible TX driver bit to assist with immediate installation on your next decking project.
Frequently asked questions
Will these screws rust if my garden stays damp?
No, because they are made from non-corrosive stainless steel. This construction is specifically chosen to resist oxidation in wet British climates, ensuring the fixings remain structurally sound even when exposed to constant moisture or heavy rainfall.How do I ensure the boards sit flat without gaps?
The triple-thread design is key here. While the first thread grips the joist, the second thread pulls the swarf down into the timber, which allows the top board to sit perfectly flush against the substrate.Can I use these with standard pressure-treated timber?
Yes, these are suitable for both composite decking and pressure-treated timber boards. The mushroom head design helps to prevent the wood from splitting during installation, making them a versatile option for various outdoor flooring types.Do I need to buy a separate screwdriver bit?
You do not need to purchase extra tools for the drive. Each 200 pack comes supplied with a TX driver bit, so you have everything required to begin fixing your boards to the joists immediately.
