What Is The Best Way To Screw Down Decking

Screwing down decking is a popular method of securing deck boards to the joists. Screwing down decking is not difficult to do, but you need to be careful when doing it correctly. By following away, you can screw down decking easily.

Decking Material Options

Decking materials include wood, composites, plastics, and metals. It’s crucial to select the material that best meets your demands and preferences because each material has a unique combination of advantages and disadvantages. For instance, wood is a preferred material since it is organic and has a warm, rustic appearance.

However, to maintain its beautiful appearance, it needs routine upkeep. Composite decking is a good option if you want the look of wood but don’t want to deal with the upkeep, while plastic and metal decking are low-maintenance options that won’t weather or rot like wood can.

Preparing the Deck for Screwing Down

You will need to start by ensuring that the deck is properly prepared for screwing down. This includes cleaning it and making sure it is clear of any dust or debris. Additionally, you must make sure that the decking is properly sealed if you are utilizing new decking.

Before continuing, apply a coat of sealer to the decking’s two sides and let it dry completely. If you are using an existing deck, it is important to check for any rotting or warping boards. These boards will need to be replaced before you can proceed with screwing down the decking.

Fastener Types and Fastening Techniques

There are three main types of deck fasteners: nails, screws, and hidden fasteners. Screws are the best type of fastener to use because they have a higher pull-out strength than nails. In addition, screws will not rust, which is a problem with nails.

When fastening deck boards, use a star drive bit to countersink a screw below the surface of the deck board This will lessen the likelihood of the screw fracturing the board. The best way to countersink screws is to use a drill/driver and a depth stop. Every time the screws are inserted, the correct depth will be achieved.

Pilot Hole Marking and Drilling

Mark the locations where the screws’ pilot holes need to be drilled. To ensure accuracy, you should measure with a tape measure and pencil. Every post should be marked on both sides with two screw locations. Make sure that these are equidistant from each other, and about 2 inches from the post edge.

Screwing Down Decking Boards

There are several methods for doing this, but here’s one of the most popular:

  1. Start by attaching two screws per board, one at each end. Consequently, the boards will remain aligned and secure. 
  2. Add a screw every 3-4 inches along the length of the board. Make sure your screws are not too close to the edge of the board or else you risk splitting it.
  3. If you are screwing down your boards, you should use corrosion-resistant screws. These are designed specifically for outdoor use and can withstand moisture and extreme temperatures better than regular screws.

 Also, be careful not to over-tighten your screws, just snug them down so they stay secure.

Finishing Off the Deck with Trim Boards

Before you attach the trim boards, use your circular saw to make sure that the edges of all of your deck boards are in line. You want to make sure that you have a nice, even line to attach your trim boards. Once that’s done, measure and cut your trim boards to fit around the edge of your deck.

Then use a level and caulk gun to make sure all of your trim board pieces are level and evenly spaced before you start screwing them into place. Using longer screws will help ensure they stay tightly in place. Once all of your pieces are secured, you can add some sealant or paint for an extra touch of protection from weather elements.

Tips to Ensure a Secure, Long-Lasting Deck

The right screws can make all the difference when it comes to making sure your deck is secure and long-lasting. Here are some tips to help you:

Grooved vs Ungrooved Composite Decking
  • If you want to use screws outside, you should use outdoor-specific screws. These will generally be galvanized to help prevent rust, and they should have a corrosion-resistant coating like zinc, copper, or stainless steel.
  • A standard recommendation is to use screws that are an inch and a half longer than the thickness of your boards. The screw will have enough space to bite into the wood joists in this way.
  • To make sure your deck is extra secure, you’ll want to space your screws properly as well. When laying decking boards, put screws about every 8 inches along each board. This will ensure maximum hold and keep your deck from shifting over time.


Here you have it: the best method for screwing down decking. If you follow these simple steps, your decking will be secure for years to come. Remember to always use the right tools and to take your time, a job well done is worth the extra effort!
