SPAX Decking Screws 5x40mm A2 304 Stainless Steel are the professional's choice for timber decking construction. Engineered in Germany with SPAX's exclusive T-Star Plus drive and precision cylindrical head, these screws deliver a clean, flush finish every time — with no pre-drilling required on most timbers.

Key Benefits

• A2 304 Stainless Steel — superior corrosion resistance for outdoor decking exposed to the elements, including coastal environments.
• T-Star Plus Drive (T25) — exclusive to SPAX. Provides a positive, secure bit engagement for better driving torque and reduced cam-out.
• Cylindrical head (7mm) — countersinks cleanly into timber with minimal splitting, leaving a neat, professional finish.
• Fixing thread — locks the decking board firmly in place, minimising cupping, squeaking, and movement over time.
• SPAX Ground Serration Thread — allows quick and easy fastening with reduced driving torque.
• CUT Point Tip — no pre-drilling required on most timbers. Reduces splitting and driving torque.
• Box of 200 — great value for decking projects.

Ideal Applications

The 40mm length is ideal for thinner decking boards, composite decking, and applications where shorter penetration is required. Perfect for hardwood and softwood decking, pergolas, and outdoor timber structures.
