Decking screws

Decking screws are purpose-designed fasteners used to secure decking boards to timber or composite subframes. They differ from standard wood screws in their corrosion resistance, self-countersinking heads, and thread design, which reduces board splitting. Builders use decking screws across outdoor construction, including garden decking, balconies, walkways, and timber-framed platforms. These screws are also used for hidden-fix systems where a flush finish is needed.

A wide range of decking screws are available, including stainless steel for high-moisture areas and coated carbon steel for treated timber. Options vary by length, diameter, and drive type, with torx and square drive heads offering better grip and reduced cam-out. Some feature serrated threads or notched tips to make application easier and reduce the need for pre-drilling. You’ll find decking screws for both softwood and hardwood decking available.
