Decking screw - A2 stainless steel - Ø 4.8 - TX 20 - countersunk head

Professional Timber Fastening: Inox A2 Stainless Steel Decking Screws

Achieving a durable and aesthetically pleasing terrace requires fasteners that can withstand the elements while maintaining structural integrity. These decking screws are manufactured from A2 stainless steel, providing superior protection against rust and corrosion in outdoor environments. The countersunk head is designed to sit flush with the wood surface, creating a smooth finish that is safe for barefoot traffic and visually seamless.

Advanced Engineering for Easy Installation
Equipped with a specialized "Cut" point, these screws significantly reduce the risk of the wood splitting during insertion. The point acts as a drill bit, clearing away fibers as it enters, which allows for a faster and smoother drive. The TX 20 (Torx) drive system ensures maximum torque transfer from your power tool to the screw, preventing cam-out and protecting the head from damage during heavy-duty applications.

Reliability and Compliance
These screws are designed to meet the rigorous requirements of the DTU (French professional building standards) for wooden decking. Whether you are working with natural timber or softwoods, the combination of the A2 material and the TBS-Drill geometry guarantees a professional-grade installation that will remain stable for years to come.

Key Advantages:

• Corrosion Resistance: High-grade A2 stainless steel prevents rust in outdoor conditions.

• Anti-Splitting Technology: The Cut point reduces internal pressure in the wood during fastening.

• Superior Grip: TX 20 drive provides a secure, wobble-free connection with your drill bit.

• Professional Finish: Countersunk head allows for a flush or slightly recessed installation.

• DTU Compliant: Engineered to meet strict building standards for structural safety.

Technical Characteristics

• Diameter: 4.8 mm

• Material: Inox A2 Stainless Steel

• Head Type: Countersunk (TBS-Drill)

• Point Type: Cut Point (Self-drilling)

• Available Lengths: 60 mm and 70 mm

• Application: Exterior wood decking and timber structures

Installation Tips

• Pre-drilling: While the Cut point reduces splitting, pre-drilling is highly recommended for exotic hardwoods or at the ends of boards to ensure a perfect, crack-free finish.

• Screw Selection: For standard 21 mm thick decking boards, a 60 mm screw is typically used to ensure sufficient penetration into the supporting joists.

• Drive Depth: Use a depth stop or careful trigger control to ensure the countersunk heads are driven to a consistent depth across the entire terrace.

• Corrosion Note: A2 stainless steel is ideal for standard outdoor use. For coastal areas within 5 km of the sea, A4 stainless steel is recommended for maximum salt resistance.
