Building a Deck? How to Choose the Right Fasteners

Last Updated on October 5, 2023 by Marsh Fasteners

A deck can boost the aesthetic appeal of the exterior portion of your home, adding to its curb appeal and increasing its overall value should you decide to sell in the future. A deck also increases the square footage of your living space, giving you more room to enjoy several activities, like relaxing, enjoying meals with loved ones, and appreciating your yard's beauty. 

There are many important decisions to make when it comes to building your deck from scratch. One of those decisions is choosing the right fasteners. 

Nails vs. screws

You will need a wide variety of nails if you use them in the construction of your deck. For example, you might require common nails, spiral nails, and/or finishing or casing nails. Most decking experts will recommend that you opt for screws, and decking screws, in particular, instead. Decking screws are self-sinking and usually feature a special coating to protect against corrosion. If possible, try to buy decking screws that can be machined with a square head as these tend to drive more securely for improved longevity. 

Invisible deck fastening systems

Some homeowners strive to avoid the look of visible nails and screws on the surface of their deck. In this instance, they would go in search of invisible deck fastening systems. The reality is that these systems generally mean an extended installation time frame; however, they provide the cleanest, most aesthetically pleasing final result. 

Heavy-duty screws and bolts

The lag screw or bolt is the king of heavy-duty fasteners, hence the reason why many homeowners turn to these fasteners when looking for maximum durability. You should always use them when securing ledger boards to walls and joists to posts. Just remember to place a washer underneath the head of the lag screw to prevent it from gradually sinking into the wood. 

Another viable option for enhanced durability is the carriage bolt. It works similarly to the lag screw and requires a washer underneath the nut. 

Factors to Consider When Choosing a Fastener for Your Deck

Compatibility of Materials

The compatibility of the chosen deck fasteners with the selected materials is one of the main factors to consider. It's crucial to ensure the fastener material complements the decking material you're utilizing perfectly. This compatibility is essential for your deck's aesthetic, preventing corrosion and maintaining the durability of your outdoor retreat.

For instance, due to their outstanding corrosion resistance, stainless steel screws are frequently highly recommended when working with composite and hardwood decking. This decision aids in preserving the deck's visual appeal and structural integrity over time, even when it is exposed to the elements.

Corrosion Protection

Decks may experience significant corrosion challenges, particularly if subjected to harsh environmental elements like chemicals or saltwater. It is essential to choose fasteners made from substances known for their corrosion resistance if you want to fend off the corrosive forces of nature properly.

Due to its natural resistance to the corrosive effects of moisture, chemicals, and salt, stainless steel fasteners are preferred in such circumstances. Coated fasteners are another well-liked choice for people wishing to preserve their deck against corrosion, which gets a protective layer during production.

Capacity for Bearing Loads

The fasteners you choose must support the combined weight of your deck, the furnishings that will adorn it, and the people who will use this outside space. It is crucial for maintaining the structural integrity and safety of your deck that the fasteners you choose are up to the task.

By ignoring this factor, you risk having fasteners come free or break, compromising both the stability of your deck and the safety of its users. As a result, load-bearing capacity must be carefully considered when choosing fasteners.

Fastener Type

Nails, screws, and concealed fasteners are just a few of the deck fasteners available. Your decision needs to align with the specific kind of deck you're building and the style you want. Each type has particular benefits to take into account:

  • Nails: These are excellent for several deck applications since they are conventional and frequently affordable. They might not, however, offer screws' level of durability and holding force.
  • Screws: Due to their greater functionality, specialists frequently suggest screws, particularly decking screws. Self-sinking decking screws often have a unique coating that increases their corrosion resistance. Use decking screws that can be manufactured with square heads for more extended durability and safer driving.
  • Hidden Fasteners: These solutions appeal to individuals who like a seamless, clear deck surface free of obvious fasteners. Even though they produce a tidy and attractive end product, these systems can necessitate a lengthy installation period. The work may be well worth the outcome.

Size and Length

Choosing the proper length and size of pins is essential to achieve a secure connection without unfavorable results like wood splitting or fasteners protruding through the opposite side. Paying close attention to this detail is necessary for your deck's safety and overall aesthetics.

The deck's structural integrity may be compromised by fasteners that are too short because they may need to offer more grip and stability. On the other hand, too long pins might cause splintering and provide a less-than-optimal surface. Therefore, accuracy in determining the proper length and size is essential for a deck project's success.

Every choice, including choosing the appropriate fasteners, has significance in deck construction. You can ensure that your deck project is successful by carefully considering elements like material compatibility, corrosion resistance, load-bearing capability, fastener type, length, and size. Your deck will serve as a lovely, secure, durable outdoor sanctuary and testify to your craftsmanship. Aesthetic and practical considerations for head style

Head Style

The head style of the fasteners you select can affect your deck project in an aesthetic and functional way. You have several head style options to consider depending on the type of deck you are building and your design preferences. Here, we examine the role that head style plays in deck building:

Aesthetic Appeal: The head design of the fasteners dramatically impacts how your deck looks as a whole. Various head styles can produce unique visual effects. For instance, flat-headed fasteners can be the way to go if you desire a clean, minimalistic look. Countersunk or pan-headed fasteners provide a more conventional or decorative appearance. Your selection should complement your preferences and your deck's design motif.

Beyond aesthetics, there may be functional ramifications for the head style. The risk of tripping or snagging on elevated fasteners can be decreased, for example, using flat-headed screws or nails that sit level with the deck surface. This can be very important if your deck has a lot of traffic or small children who may be more prone to accidents.

Thread Type

When working with various types of wood, the thread type of your fasteners is extremely important to take into account. For your deck building to be secure and long-lasting, it is imperative to understand the relationship between thread type and wood kind:

  • Fasteners with coarse threads are renowned for having exceptional holding power in softwoods. The grain patterns of softwood species like pine, cedar, and redwood are typically bigger and softer. Coarser threads can grab more firmly in these woods and offer a dependable, strong connection.
  • Hardwoods, where the grain is tighter and denser, are better suited for fine-threaded fasteners. The finer threads are advantageous for hardwood species like oak, ipe, and mahogany because they can penetrate and engage with the wood more effectively without producing severe splitting.

The fasteners will function properly and help avoid potential problems like wood splitting, which could jeopardize the structural integrity of your deck if the thread type and wood type are matched.

Cost: Juggling Investment and Durability

Despite the attraction of cost-cutting strategies' allure, it's critical to remember that constructing a deck is a long-term investment. Although quality fasteners may cost more upfront, they can save you money on repairs and upkeep throughout the deck's lifetime. When choosing your fasteners, take into account the following cost factors:

Initial Investment: Quality fasteners may have a slightly higher initial cost than their inferior equivalents. However, the increased longevity and decreased need for replacements or repairs can counterbalance this expense.

Long-Term Savings: By using robust and corrosion-resistant fasteners, you can save money and hassle by avoiding the cost and hassle of replacing pins too soon. High-quality fasteners can survive external conditions and continue to work for many years.

Total Worth: It's critical to evaluate the total cost of your deck project while determining expenses. In addition to enhancing your outside space, a well-built deck with high-quality fasteners increases the value of your house. It might be a selling point if you ever decide to sell your home.

Installation Simplicity: Juggling Convenience and Quality

When choosing fasteners for your deck, it is important to consider the simplicity of installation. A clean, screw-free surface provided by some fastening techniques, such as hidden fasteners, improves the deck's aesthetic. However, these systems could need additional time and specialized equipment for appropriate installation. Here is how to handle this situation:

  • Hidden Fasteners: These solutions offer a deck surface unencumbered by visible screws or nails. They provide a smooth and uniform appearance. However, they frequently need careful installation that calls for particular tools and exact spacing. Hidden fasteners can be a great option if you value appearance and are prepared to spend more time installing.
  • Traditional fasteners: Generally, screws or nails are simpler to install and take less time. They need common tools and need to be more picky about installation accuracy. Their heads are, however, visible, which can detract from the deck's attractiveness.

Your decision between aesthetics and installation convenience should consider your tastes, the project's schedule, and your willingness to devote time to the installation procedure.

Local Building Regulations: Promoting Compliance and Safety

To be sure the fasteners you select meet any requirements, always verify your local building standards and regulations. It's essential to follow local laws for both legal and safety reasons. Here is how to handle this situation:

Local construction codes are frequently created with consideration for safety. They specify the requirements to guarantee your deck's structural integrity and usability. To protect those using your deck, fasteners must meet or exceed these specifications.

Legal Compliance

Disregarding local building regulations may result in legal repercussions and delay your project. It's crucial to secure the required permits and guarantee that the construction of your deck complies with local laws.

Fluctuations in Temperature

Taking Environmental Factors into Account

It's critical to use fasteners that can withstand material expansion and contraction if your deck will be subjected to drastic temperature variations. Temperature changes can impact the integrity of the fasteners and the deck's general stability. Here is how to respond to this issue:

  • Installation Techniques: Pay strict attention to the installation procedure, mainly when working with temperature-sensitive materials. Temperature changes can be lessened by adhering to manufacturer recommendations and allowing for adequate separation and mobility.
  • Aesthetics: Think about how the fasteners will look once the deck is finished. The visual component is a matter of taste and can significantly impact the overall layout of your deck. Here are some things to think about:
  • Visible Fasteners: Traditional fasteners can be helpful if you don't mind how visible screws or nails look. They offer an uncomplicated, practical appearance.

Hidden fastening techniques are best for a smooth, unobstructed deck surface without apparent fasteners. They produce a smooth and attractive finish that lets the beauty of your deck's components stand out.

Your decision regarding visible or hidden fasteners should align with your design goals and desired aesthetic result.

Manufacturer Advice: Seek Professional Advice

Always read the instructions provided by the manufacturer for the fasteners and the decking material. To ensure compatibility and performance, manufacturers frequently offer particular suggestions. Why this step is crucial is as follows:

Manufacturers are the only ones who truly understand their products. Their suggestions are made to guarantee that the fasteners are compatible with the selected decking materials. Not following these suggestions closely can result in compatibility issues and future concerns.

Considerations Regarding Warranties

In many cases, keeping any warranties attached to your decking materials depends on adhering to manufacturer instructions. Using non-manufacturer-approved fasteners can violate guarantees and leave you helpless in the event of problems.
