Deck fasteners, also known as deck screws or deck nails, are an essential element of any deck construction. They secure the deck boards to the substructure, holding everything in place and providing stability and safety. However, excessive use of deck fasteners may lead to various issues, including board damage. In this article, we will explore the potential implications of using too many deck fasteners and how to prevent such damage.
Understanding deck fasteners and their purpose:
Deck fasteners are designed to hold the decking boards securely to the underlying structure. They come in various types, such as screws, nails, and hidden fastening systems. The purpose of these fasteners is to ensure the deck boards remain stationary and do not shift, warp, or become loose over time. They distribute the weight of foot traffic evenly across the boards, preventing potential issues like sagging or unevenness.
The dangers of excessive deck fasteners:
While deck fasteners are crucial for the structural integrity of a deck, using too many of them can lead to several problems:
- Board splitting: Excessive fasteners, particularly screws or nails, can cause the deck boards to split or crack. When too many fasteners are used close together, the stress applied during installation or due to changes in temperature and humidity increases. This additional stress can lead to wood splitting along the grain, compromising the strength and lifespan of the boards.
- Warping and cupping: Overuse of fasteners can interfere with the natural expansion and contraction of the deck boards due to environmental factors. As wood absorbs and releases moisture, it swells and contracts. Too many fasteners restrict this movement, resulting in warping, cupping, or bowing of the boards. This not only affects the aesthetics but also increases the risk of tripping and potential injury.
- Uneven weight distribution: When deck fasteners are spaced too closely, the weight of foot traffic is distributed unevenly across the boards. This can cause some areas to bear more weight than others, leading to accelerated wear and tear and potential structural issues. Over time, this uneven weight distribution can cause the boards to degrade and compromise the overall stability of the deck.
Preventing board damage from excessive fasteners:
To prevent damage to deck boards from excessive fasteners, consider the following measures:
- Follow manufacturer’s guidelines: Always consult the manufacturer’s instructions for recommended fastener spacing and installation procedures. These guidelines are typically based on extensive testing and research to ensure the optimal performance and longevity of the deck boards.
- Use hidden fastening systems: Consider using hidden fastening systems that attach the deck boards from below the surface, such as deck clips or hidden screws. These systems distribute the fixing points evenly and minimize the risk of splitting or warping.
- Proper spacing: Strive for consistent spacing between fasteners, ensuring they are evenly distributed along the length of each board. This spacing allows for natural expansion and contraction of the wood while maintaining stability and preventing warping.
- Quality materials: Invest in high-quality deck fasteners made specifically for outdoor use. They should be resistant to corrosion and designed to handle the environmental conditions your deck will face.
While deck fasteners are essential for the stability and safety of a deck, excessive use can lead to various issues, including board damage. Board splitting, warping, and uneven weight distribution are some of the consequences of using too many deck fasteners. However, by following manufacturer’s guidelines, using hidden fastening systems, proper spacing, and quality materials, you can prevent such damage and ensure your deck remains durable and aesthetically pleasing for years to come.
