Decking Screws

A decking screw isn't just a screw that happens to be used on a deck - it's a purpose-engineered fastener designed specifically to perform in the hostile combination of outdoor conditions, timber movement, and foot traffic loading that a deck faces. At the DIY Hardware Store, our decking screws range covers the coated and stainless steel screws used for fixing softwood and hardwood deck boards to their supporting joists and frame.

Standard zinc-plated screws corrode rapidly in outdoor conditions; decking screws use a green polymer or hot-dip galvanised coating, or are made from stainless steel (the correct choice for hardwood decking, where tannins can accelerate corrosion in lesser finishes). A sharp, self-drilling point and a bugle head that sits flush without tearing the timber surface are equally important.

  • Green coated and hot-dip galvanised for softwood decking
  • Stainless steel for hardwood and composite decking
  • Bugle head sits flush without tearing timber
  • Self-drilling point for clean entry without pre-drilling
  • Resists corrosion and staining caused by timber tannins
  • Available in standard deck board lengths and gauges
