The choice fastener for hardwood decking is a stainless steel screw. Other options like galvanized screws may stain the wood black around the screw head. When face-screwing Ipe, Massaranduba, Cumaru or Garapa, the installer should pre-drill a starter hole equal the diameter of the screw shaft. The threads should only engage the softer joist below. Two screws should be set per each joist near the outer edges of the deck board.
A #7 or #8 is standard for general construction. We stock #7 for standard hardwood decking, but may special order any size your job requires.
What Type of Screw head?
There are two types that are used – flat head and trim head. Trim head screws are more common and take up a tighter profile. They work well with exotic species as long as you pre-drill a pilot hole.
Since hardwood decking is typically 1″ or 3/4″ net thickness, 2″ to 2-1/2″ is a standard length range. Depending upon your installation requirements, you may need to go as short as 1-5/8″ or as long as 3″. eDeck stocks varying lengths, but the standard will be a 2-1/4″.
How Can I Hide the Screw Head?
If you do not want the screw head showing on the surface of a face-screwed deck, then you have several options:
- Use a “color head” screw. These screws have a colored epoxy coating over the heat to help create a lower profile.
- Use plugs. You can create a divot into the deck facing with a 3/8″ countersink tool, set your screw, then glue a 3/8″ plug to conceal the fastener. This is more time consuming but gives a nice aesthetic.
- Try a hidden fastener, such as the CAMO System, EB-TY® or Ipe Clip® Extreme™.
