When attaching your Ultradecking board to the joist, it is better to screw it down. Screws hold your decking in place; it will also make the decking board last for a long time. If you use screws for your decking, you don’t have to bother whether it will shift from its position. Apart from that, using screws is a good option for nails and clips. The nail can pop up over time, thereby ruining your deck. At the same time, clips can also be difficult to use. Let’s see why screwing your decking is preferable to other methods. We will also consider how to screw down decking boards properly?

Why Screwing Decking Board is Better

Firstly, decking screws are preferable to nails because screws will grip your deckings better. Screws are not attached to decking boards like nails. Rather it is twisted into the decking, thereby gripping the board well. The expansion and contraction of a wooden board can slowly push nails upward, thereby causing the head to pop. But screws, on the other hand, will still hold on to your decking when the decking expands and contracts. The screws won’t pop out like if you use nails.

Secondly, screws also help to keep wood from cracking. Apart from that, it also minimises cupping. The screws will hold down your decking board, thus preventing the edges from curling up. When you screw down your decking board, it will prevent cupping, thereby extending the lifespan of your decking.

Lastly, the reason why you should use screws is that screws will hold your board in place. When the decking swells due to high moisture content, it will push the nail up. But for screws, their heads are designed to keep the decking in place when it swells.

How to Screw Down Decking Board

It’s easy to screw down your decking. If you want to know how to fasten your decking board yourself, follow the steps below.

Step One: Pick the Right Screw

Start by picking the right decking screw. Wood decking boards contain chemicals that can be corrosive to fasteners. When you want to screw down your decking, you should choose a screw that is resistant to corrosion.

Stainless steel screws are good for holding decking boards in place. They are resistant to corrosion and will not rust. There are also polymer-coated screws; they come in various colours that will blend with your decking board. Now that you have your screws at hand, you can then proceed to use them to hold your wood decking in place.

Step Two: Pre-drill the Decking Board

Start by making holes on your decking board. The hole should not be too wide. It should be about 2 mm smaller than the screw you are using. Use a power or manual drill to make holes in your decking. If you are using softwood as your decking board, drill the holes at the decking end only. If your decking board is from hardwood, you must pre-drill the wood to drive the screws in.

Pre-drilling your decking before you screw it down will prevent the wood from splitting. Wood can crack or splinter, remember? So making holes in the wood before inserting the screws will keep that from happening.

Step Three: Screw Down the Decking Board 

After you have finished pre-drilling the wood, proceed to screw the decking down to the frame. Use a screwdriver to fasten the screw into the decking board.


It is good to screw down decking boards instead of using nails. You can fasten your decking boards by first making pilot holes in them; after that, use a screwdriver to drive the screws in.
