Walk a deck barefoot, drag a broom across it, then glance down the length of the boards, and between them the three show how the boards are fastened. A row of small round heads or wood plugs marching down every joist line means face screws. An unbroken surface with only the gaps between boards showing means the fasteners sit underneath, out of sight. Both methods hold solid wood boards to the joists, and both are sound carpentry. They differ in how firmly each pins a board, how much room the board has to move, and what the surface looks like after a few seasons of weather.
How a Face Screw Holds a Wood Board
A face screw is driven straight down through the top of the board and into the joist beneath it. Two screws go in at every joist the board crosses, each set about an inch in from an edge, so each board is pinned to the framing at both of its edges, again and again along its length. The threads bite into the joist, and the head, set slightly below the surface (countersunk), clamps the board down against it.
That clamp is the strength of the method. A board held at both edges at every joist has very little freedom to lift or slide, and a face-screwed board is held more firmly than a board on edge clips.
The cost is on the surface. Every head leaves a small recess in the board's face. Left open, the recess shows as a dot; filled with a wood plug cut to match the species, it shows as a smaller dot with a slightly different grain. Either way, the fastener pattern remains part of the deck's look for the life of the boards.
Screws for a deck built from treated lumber need a corrosion-rated coating or stainless steel, and that holds for either method in this comparison.
How Hidden Fastening Holds the Same Board
Hidden fastening keeps the hardware off the walking surface, and the systems hold a board in two different ways. An edge clip sits in a groove along one edge of the board and is fixed to the joist, and the next board closes over it, so on many clip systems that edge carries the board and the other edge is left free to float. A side-screw system drives a screw at an angle through each edge of the board into the joist, so the board is held at both edges, closer to a face screw, with the heads out of sight.
In a clip system, that single-edge hold explains most of what the method does, both well and badly. The surface comes out smooth, with no heads, no plugs, and nothing to catch a broom. The hold on each board is lighter than that of a face screw because one edge carries the board instead of two. How well a deck does with hidden fasteners leans on the board itself: narrower, thicker boards give a single-edge hold more to work with, while wider boards ask more of it than it can give.
Swelling, Shrinking and the Weather
Solid wood boards take on moisture and swell, then dry out and shrink, all the time. Kiln-dried boards do it too. A fastener has to live with that movement for as long as the deck stands.
A face screw pins both edges, so the board stays tight to the joist and the movement has to go somewhere. It goes into the screws: over the seasons, a board working against its screws can loosen the threads or let a head back up toward the surface. A deck that sits through long damp spells moves its boards more than one kept in drier air, and the more a board moves, the harder it works its fasteners. In a deck kept in dry air, the boards swing less, and a face screw stays settled longer.
A clip system gives the movement a way out. Because one edge floats, a board can swell and shrink across its width without pulling against a screw at each edge. The flip side is the same freedom: a board that wants to shift or lift at its free edge is held by a lighter hook, so a board that moves a lot is asking more of the method. In a damp deck, the choice between the two is a trade-off between a firm pin that gets worked and a light hold that lets the board move.
The crew looks at the boards themselves, and at how much weather the deck will see, before settling the question.
How Each Feels and Looks Underfoot
Bare feet are the plainest test. A countersunk head sits just below the surface and does not catch a foot, but a head driven a little proud of the board does, and so does the edge of a plug that has lifted. A broom drags on both. Hidden fastening leaves nothing on the surface to snag, which suits a deck where children play barefoot, or a dog's nails scrape across the boards all day.
From a few steps back, the difference is about rhythm. Face-screwed boards show a regular dotted line at every joist, which some owners like because it reads as a built deck and others find busy. Hidden fastening gives long clean lines with only the board gaps to read. Neither look is better in itself, and the choice follows what the owner wants to see out of the kitchen window.
Plugs weather differently from the boards around them, so a plugged deck can keep a faint pattern even when the plugs were cut to match.
Face Screws and Hidden Fasteners Compared
The table below sets the two methods side by side on solid wood boards.
| Question | Face screws | Hidden fastening |
|---|---|---|
| How the board is held | Pinned at both edges at every joist | Clips: one edge, the other floats; side screws: both edges |
| Holding strength | The firmer hold | Lighter on clips |
| Board movement | Taken up in the screws and the board | Clips: taken up by the free edge |
| Surface | Heads or plugs in rows | Smooth, no hardware showing |
| Barefoot and broom | Fine when heads sit flush | Nothing to snag |
| Boards it suits | Wider boards, boards prone to move | Narrower, thicker boards |
A single board that has to come up later can be freed under either method, and the crew works out the fasteners holding it when that day arrives.
Before the estimate, press a bare foot along a board edge and across a joist line on a deck you like. A head standing proud or a board that shifts shows up at once.
Board, Setting and Taste on the Visit
The decision is made in person, because the answer sits in the boards and the setting. On the visit, the crew looks at four things.
Board width and thickness: Wider boards lean toward the firm pin of a face screw, while narrower, thicker boards give a hidden fastener more to work with.
Exposure: A deck in full sun, a deck in deep shade, and a deck that stays damp each move their boards differently, and the fastener has to suit the board's likely movement.
Use: A deck built for bare feet and a deck that mostly holds furniture ask for different surfaces.
The look you want: A dotted joist line or a smooth field.
The crew chooses on the visit once those four are on the table. Nothing about the choice is locked in before someone has seen the boards and the space.
A fastener choice is a small decision that the deck lives with every day, in the sound of footsteps, in the feel of a board edge and in how the deck looks as the seasons move over it. A method that suits the boards and the weather they will see is the one that still looks settled years later.
Frequently Asked Questions
Is there a middle path between bugle-head screws and fully hidden fasteners?
Yes. A trim-head screw has a much smaller head than a standard deck screw, so the dot on the board face is small, and it still goes through the board face into the joist. It grips fairly well in dense wood, though its small head provides the board with less clamping area than a full-size head.
Does a hidden system need special boards?
Some hidden clips engage a groove cut along the edge of the board. Some boards arrive pre-grooved; otherwise, a slot can be cut with a biscuit cutter. A board without that groove or slot has no place for the clip to engage, so the system and the board have to be matched before the deck is built.
Are all hidden clips made the same way?
No. Some are all stainless steel, and some carry plastic parts; an all-stainless clip stands up to the weather better than one with plastic.
Does it matter how close the deck sits to the ground?
Yes. Some clip systems are not meant for a deck with under about 30 inches of clearance, or one without air moving beneath it on at least three sides, because boards over damp, still air stay wet, and wet boards lean toward face screws. A deck with a tall open space beneath and good drainage under it suits hidden fastening better.
Does a narrower board really give a hidden fastener more to hold?
Yes. A board about 4 inches wide crosses the same width of deck in more pieces than a 6-inch board, and each extra board edge is a place to fasten. Across the same area, there are about half again as many fastening points, which is why narrow, thick boards pair well with hidden fastening.
Does a thin 1x6 board change the answer?
It does. A nominal 1x6 is only about 3/4 inch thick, so a clip in its edge has less wood around it than in a thicker board, and a thin board six inches wide leans toward face screws.
