200 wood decking screws – Inox A2 – cylindrical head T-STAR+ T25 – 5x50 mm

Professional fastening for durable timber terraces

SPAX universal screws are designed to meet the highest standards of timber construction. Crafted from Inox A2 stainless steel, they offer optimal resistance against rust and environmental wear, making them ideal for long-lasting outdoor structures. The 5x50 mm dimensions are perfectly balanced for standard decking boards, providing deep anchorage and structural security.

High-performance engineering for a perfect finish
Every element of this screw is optimized for speed, safety, and visual appeal:

• Dual-thread technology: The fixing thread consists of a main thread and a secondary under-head thread. This unique configuration clamps the board firmly to the joist, ensuring a secure fit that eliminates creaking and prevents the boards from loosening over time.

• 4CUT point: The specialized tip allows for driving without the need for a pilot hole in most wood types. By displacing the wood fibers rather than splitting them, it significantly reduces the risk of splicing or cracking near the edges.

• T-STAR plus drive: The T25 internal drive system offers exceptional bit seating and guidance. This is particularly effective for overhead work or high-torque applications, preventing bit slippage and protecting the screw head.

• Cylindrical head design: The small, decorative head sinks effortlessly into the timber fibers, providing a discreet and flush finish that highlights the natural beauty of the wood rather than the hardware.

Key advantages:

• Inox A2 stainless steel: Maximum protection against corrosion in outdoor settings.

• Anti-creak design: Fixing thread keeps boards tight and silent.

• Split prevention: 4CUT point protects the integrity of your timber.

• User-friendly: T-STAR plus interface for safe and rapid installation.

Installation tips

• Bit selection: Always use an original SPAX T-STAR plus T25 bit to ensure the most stable connection and to prevent premature wear of the screw drive.

• Hardwood note: While the 4CUT point reduces splitting, we recommend a test drive or pre-drilling when working with exceptionally dense exotic hardwoods to achieve the cleanest possible entry.

• Board alignment: Space your screws consistently across the terrace surface to ensure a professional, symmetrical look.

• Depth setting: Adjust your drill's torque or use a depth stop so the small cylindrical head sits just flush with the wood surface, avoiding "over-driving" which can create water-collecting pockets.

Note: This box contains 200 screws. Ensure your project calculations for joist spacing and board width are verified to determine the total number of boxes required.
