Buildex® Self-Drilling Decking Screws

The typical practice for fastening decking boards to timber subframes involves pre-drilling and pre-countersinking prior to attaching the decking board to the joist with a standard decking screw. This practice is commonly used as hardwood decking boards are dense in nature which can result in splitting the deck board when fixing close to the edge. Alternatively, it can snap a typical decking screw due to the torque required to penetrate hard timbers. With a standard deck requiring up to 1500 decking screws this labour-intensive practice takes up a lot of time.

We know your time is valuable and you want to complete a job with a premium finish.

The Buildex Self-Drilling Decking Screw lives up to its name. This new decking screw incorporates several design features that delivers optimum performance for self-drilling non-split performance, speed, and ease of installation resulting in a beautiful finish & ultimately – giving you your time back.

  • Quick Drive Point for faster installation and to prevent deck boards from splitting. It allows precise positioning to reduce “walking” when placing the screw on the board and effectively penetrates 50% into hardwood deck boards before the thread engages.


  • Serrated & Super Thread rapidly cuts timber into small fibres to reduce splitting, while drawing out timber fibres to reduce driving torque.


  • Clearing Thread enlarges the hole to reduce friction on the shank of the decking screw as it prepares for countersinking.


  • Trim Head minimises pressure on deck boards when embedding and features a T20 Star Drive that offers positive bit engagement and more resistance to “cam-out”.


  • Cutting Nibs under the head enhances the overall appearance of the deck by providing a clean and flush finish.
