German made SPAX decking screws use a double thread fixing technology to hold the board down, preventing movement of the board in hot or wet conditions & preventing screw heads popping up out of your deck. The ease of installation, the quality of the finish & the lifetime durability is the reason SPAX screws are used by professional builders, councils & government organisations across New Zealand.

These screws are for use with timber joists such as merbau but we also stock decking screws for steel joists and aluminium joists.

What size do I need?

It’s important to select the correct screw length for your board. Use this table to work out the longest screw you can use that doesn’t exceed your maximum board thickness.

You can work out how many screws you need for your project by using the decking screw calculator.

304 or 316 stainless steel For most projects we recommend 304 grade stainless steel. 316 stainless steel is suitable if your screws have direct contact with ocean water or are being submerged. If you are off the coast and at most get ocean spray, 304 is suitable.
