Choosing the Right Decking Screws
Building a deck is a substantial investment, and the choice of fasteners plays a pivotal role in its longevity and aesthetic appeal. Here are some key considerations when selecting decking screws:
Material: For longevity, stainless steel decking screws are highly recommended. Steel & Tube recommends 304 stainless steels for most applications, but when working with hardwoods high in tannins or in coastal areas, opt for the more corrosion resistant T316 stainless steel to prevent timber reactions.
Head Type: Choose between countersunk (csk) and raised countersunk (raised csk) heads. Both can be flush-mounted, but raised head screws can be used to create a different visual effect.
Diameter: Most opt for 10-gauge (10g) screws, but 12-gauge (12g) screws are more common for wider decking materials.
Length: The most common length is 60mm, suitable for most decks. Ensure a minimum of 40mm embedment, leaving a maximum of 20mm of decking material exposed. Use longer screws for thicker decking material.
Proper Pilot Hole Drilling
To prevent wood splitting, it's crucial to drill pilot holes of the correct size for the screw's diameter. Consider using a Starborn depth-setting Smart bit for this purpose. Drill pilot holes approximately 20mm from each end of the decking board. While wood may not split immediately, it can occur over time due to the natural expansion and contraction of wood with changing temperatures.
60 second tip: Use a driver bit compatible with your chosen decking screws. When driving screws, avoid overdriving them. It's advisable to use a drill with a clutch instead of an impact driver to ensure precise control. Install screws at consistent intervals, securing them into each joist for optimal stability.
