100 Wood Decking Screws TFB – Inox A2 – 5.0x70/46 – TX25 – CUT Point – T-Drill

High-end fastening for heavy timber and hardwood decking

Designed for durability in challenging outdoor environments, these Inox A2 stainless steel screws provide the ideal combination of strength and corrosion resistance. The 70 mm length makes them particularly suitable for thicker decking boards or structural timber elements where a deeper anchor into the joist is required. Whether you are a professional landscaper or a demanding DIYer, these screws offer a reliable, long-lasting solution for luxury wood constructions.

Precision engineering for hardwood integrity

The TFB T-Drill range is developed to handle the high density of exotic timbers without compromising the wood's structural integrity:

• CUT point technology: The ultra-precise cutting point acts as a miniature drill, slicing through wood fibers as the screw is driven. This prevents the formation of cracks and fissures, even when fastening near the ends of boards.

• Simplified installation: These screws are designed to be used without pre-drilling in many timber types, significantly speeding up the assembly process while maintaining a clean entry.

• Stable driving experience: The TX25 (Torx) drive provides a high-friction connection that eliminates wobbling and bit slippage. This allows for smooth, consistent power transfer even into the densest hardwoods.

• Architectural finish: The small decorative head sinks flush into the timber, providing a clean and professional appearance that enhances the natural look of the terrace.

Key advantages:

• Corrosion protection: Inox A2 stainless steel for excellent durability in outdoor settings.

• Anti-fissure design: Integrated CUT point prevents wood splitting in dense species like Massaranduba.

• High tensile strength: Rated at 500 N per mm2 for maximum structural grip.

• Superior drive: TX25 internal toothing for a secure, no-wobble installation.

Professional tips

• Hardwood best practices: For exceptionally dense exotic hardwoods, a pilot hole is always recommended to achieve the cleanest possible finish and to reduce mechanical stress on the screw.

• Depth consistency: Use a drill with a depth-setting collar to ensure all decorative heads are seated at a uniform level across the entire deck surface.

• Screw placement: Position screws at least 15 mm to 20 mm from the edge of the board to minimize the risk of splitting, even with the integrated CUT point.

• Environmental suitability: A2 stainless steel is suitable for most garden environments. For projects within 5 km of the coast, A4 stainless steel is preferred to resist salt-air corrosion.
