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

These countersunk screws are engineered to prevent the "mushroom effect" often caused by standard wood screws when working with polymer composites. The saddle brown heads are colour-coated to blend with your boards. They are also treated to resist corrosion from ACQ and copper azole wood treatments. This makes them a reliable choice for long-term use in damp British climates.

Use these fasteners for installing new composite decking in domestic gardens or commercial walkways. They work well on raised platforms and patio areas. The design ensures a flush finish on both residential paths and public outdoor spaces. They are suitable for any project requiring a secure, low-profile connection between boards and joists.

The self-drilling tip means no pre-drilling is required before installation. This saves time during large garden builds. Each screw features a Torx TTAP drive system to prevent stripping during high-torque applications. Simply drive them directly into the material for a stable, professional finish.
