5.2mm x 63mm Countersunk Self-Drilling Composite Decking Screws, 350 Pack

These countersunk screws are engineered to prevent the "mushroom effect" often seen when using standard wood screws on polymer-based boards. Each screw features a colour-coated, anti-fade head in Madeira Brown to blend with your decking. The steel is treated to resist corrosion from copper azole wood treatments. This ensures long-term durability even when exposed to the damp British climate throughout the autumn months.

Use these fasteners for installing modern composite decking in residential gardens or public walkways. They work well on raised platforms and patio areas where a clean, flush finish is required. The Madeira Brown coating helps the fixings disappear into the boards. This makes them suitable for both private garden renovations and commercial outdoor seating areas.

The self-drilling design means no pre-drilling is required before installation. They feature a Torx TTAP drive system to prevent stripping during use. This helps ensure a secure grip in both timber and composite materials. Always check your subframe spacing before you begin.
