Green Box wood decking screw set – Inox A2 – Stage 2

The complete installation kit for exotic timber

The Green Box stage 2 set is specifically curated to streamline the construction of high-end wooden decks. By combining premium fasteners with precision installation tools, this kit ensures that both professional builders and DIY enthusiasts can achieve a structural result that is both aesthetically perfect and technically sound.

Advanced fastening technology

• Inox A2 corrosion protection: Every screw is manufactured from Inox A2 stainless steel, providing high resistance to rust and oxidation, ensuring your terrace remains secure and stain-free through years of outdoor exposure.

• Dual-thread system: The 5x60 mm screws feature a specialized double-threading. This design provides exceptional clamping force, pulling the decking board tightly against the joist and locking it in place to eliminate the squeaking or "walking" often associated with natural wood movement.

• Precision pre-drilling: The included 4.1 mm stepped drill bit is essential for hardwood applications. It allows you to create a pilot hole and a countersink in a single pass, preventing the dense wood fibers from splitting while ensuring the screw head sits perfectly flush.

• High-traction drive: The box includes a set of T25 (Torx) bits, designed to deliver maximum torque without slipping, protecting the integrity of the stainless steel heads during high-volume installation.

Key advantages:

• Full coverage: One box contains everything required for a terrace of up to 25 m2.

• Anti-creak performance: Double threading ensures a permanent, tight fit between wood layers.

• Professional tooling: Includes a specialized stepped drill bit and multiple T25 bits to prevent project downtime.

• Optimized for hardwoods: Specifically engineered for the density and requirements of exotic timber species.

Kit contents

• 850 double-thread wood screws (5x60 A2)

• 12 spacers (shims) for consistent board alignment

• 1 stepped drill bit (4.1 mm) for precision pre-drilling

• 1 box of 5 T25 screwdriver bits

Installation tips

• Preparation: For exotic hardwoods, always use the included stepped drill bit. This prevents internal tension in the wood and guarantees that the screw head will not stand proud of the board.

• Spacing: Utilize the 12 included spacers to maintain a uniform gap between your decking boards. This allows for natural expansion and proper water drainage.

• Pedestal stability: When installing on pedestals, ensure your joists are perfectly level before beginning the "Stage 2" fastening of the boards.

• Bit replacement: With 850 screws to drive, check your T25 bit for wear periodically. Switching to a fresh bit from the included 5-pack ensures a perfect grip and prevents damage to the screw heads.

Note: This kit is designed for the board-fastening stage of construction. Ensure your sub-structure and pedestals are correctly installed before starting with the Green Box Stage 2.
