Hidden deck fasteners are a popular choice for homeowners looking to build a deck with a sleek hardwood finish, free of visible screws or nails. Concealed deck fasteners do result in beautiful decks, but there are a few things you should be aware of before you go for this option. Here are five things you should consider before installing a deck with hidden fasteners.
What are Hidden Deck Fasteners?
Hidden deck fasteners are also known as concealed deck fasteners (or even invisible deck fasteners). These fasteners are specifically designed to connect decking boards to the joists. What makes these fasteners ideal is that they don’t require visible screws or nails on the surface.
If you are looking for hidden deck fasteners, you can find them in various designs and materials, such as plastic and composite material. Stainless steel fasteners however are quite popular due to their durability and ability to work in most environments.
5 Facts About Hidden Deck Fasteners
Thinking of investing in hidden deck fasteners? Here are 5 interesting facts you should know:
1. There are times when you shouldn’t use hidden deck fasteners
Hidden deck fasteners are not always the best choice. If your project involves any of the following, you should instead use traditional stainless steel fasteners, such as face screws:
- If your deck is lower than 30 inches above the ground.
- If your deck is not well-ventilated on all sides.
- If you are using 1x6 decking boards.
- If the area below your deck doesn’t drain properly.
- If your deck boards are prone to cupping or warping.
- If you're working with exotic hardwoods or other types of decking material that are prone to excessive movement.
In these cases, it's often better to use a face-screwed installation method, which can help to hold the boards securely in place.
2. Hidden fasteners work best with narrower, thicker deck boards
When you use a hidden fastener system, only one side of each plank is fixed with a screw. This means that the side that is fastened will hold firm, while the other side will expand, contract, and move. Narrower boards are thus more suitable for these systems as they provide more fastening power per square foot.
3. Hidden fasteners are more vulnerable to natural decking movement than deck screws
Following the above point, it should be clear that decks with hidden fasteners are more susceptible to the natural movements that will result from changing weather conditions. As the boards expand and contract with the changes in temperature and humidity, they will be more likely to move as they are only fastened on one side.
4. There is a trade-off between strength and aesthetic
The main attraction to decks with hidden fasteners is that they are more pleasing to the eye. Without any visible screws, decks will have a sleek, smooth finish. However, this comes at a cost, because while the deck will look beautiful, it will also be slightly weaker than a deck that has been constructed with face screws.
5. Only some projects are suitable for hidden deck fasteners
Projects that are most suitable for hidden deck fasteners are ones where the deck is 30 inches or higher off the ground, where the ground is properly pitched and drained below the deck, and where there is adequate under-deck ventilation.
The Benefits of Hidden Deck Fasteners
There are many reasons why you should consider hidden deck fasteners for your project.
It enhances the appearance of your deck
One of the biggest reasons is that hidden fasteners are an excellent choice for anyone looking to enhance the appearance and durability of their deck. These fasteners have no visible screws or nails which helps to enhance the deck's natural beauty. It helps to elevate the deck's overall value and appeal.
Durability
It’s not just about looks – hidden deck fasteners are also incredibly durable. Unlike traditional methods, these fasteners rely on mechanical connections which offer superior resistance to rot, decay, and insect infestation. The decking boards can expand and contract naturally without compromising the fastener's strength and stability. This results in a longer-lasting and more reliable deck.
Safety comes first
Safety is also a key consideration when it comes to deck fasteners. Exposed screws or nails can be more than just unsightly. They can create tripping hazards and can snag clothing or skin. Hidden deck fasteners are therefore the best choice for families with children or pets.
Little maintenance
Hidden deck fasteners come with minimal maintenance. These fasteners reduce mold and mildew growth by preventing water accumulation between the decking boards.
How to Choose the Right Hidden Deck Fasteners for Your Project

Ease of installation

Brand reputation
If you want durable and quality hidden deck fasteners, look for fasteners manufactured by reputable brands. Ensure that the brand has a history of quality and customer satisfaction.
