Understanding the Role of Fence Pickets
Definition and Function
The beauty of a well-built fence lies not just in its visual appeal, but also in its robust construction. One of the fundamental decisions in fence building, often overlooked, is how to attach the pickets – those vertical boards that make up the face of your fence. Pickets, acting as the vertical boards, are what define the fence’s height, the spacing, and ultimately, its primary purpose. Whether you’re aiming for increased privacy, defining property lines, enhancing security, or simply adding a decorative touch to your yard, the pickets play a central role in achieving these objectives.
Materials of Fence Pickets
The choice of picket material significantly influences the aesthetic and functional characteristics of the fence. Wood, in its various forms – such as cedar, redwood, and pressure-treated pine – offers a classic, natural look. Vinyl pickets, on the other hand, provide a low-maintenance option, resisting rot and requiring little upkeep. Composite pickets combine the aesthetic of wood with increased durability. Regardless of the picket material, the method used to fasten them to the horizontal rails is crucial. The fastener’s ability to withstand weathering, resist movement, and maintain the structural integrity of the fence will directly impact its lifespan and overall performance.
The Case for Nailing Fence Pickets
Benefits of Using Nails
Nailing fence pickets has been a traditional method, offering certain advantages that make it a viable option, particularly for specific situations. While newer techniques and materials emerge, the simplicity and accessibility of nailing remain appealing to many builders.
One of the most significant benefits of using nails is the **cost-effectiveness**. Nails, typically, are less expensive than screws, making them a budget-friendly alternative, especially for larger projects where the cost of fasteners can add up. This can be a crucial factor for homeowners and contractors working within a limited budget.
Furthermore, **speed of installation** is a key advantage of using nails, particularly when using a pneumatic nail gun. These power tools can drive nails quickly and efficiently, significantly reducing the time it takes to attach the pickets. This increased speed can translate into lower labor costs, which can be a deciding factor for those paying for professional installation.
From an **aesthetic perspective**, nails can sometimes offer a cleaner look, depending on the chosen style. Smaller nail heads can be less noticeable compared to the often more prominent heads of screws. This can be particularly desirable for fences where a clean, uncluttered appearance is the goal. It’s worth noting, though, that this can be a double-edged sword, as some might find exposed nail heads less desirable.
Drawbacks of Using Nails
While nailing offers certain benefits, it’s critical to understand its limitations, especially when compared to the use of screws.
A major concern is the **potential for reduced holding power**. Nails rely on friction to stay in place, and over time, factors like weathering, wood movement, and vibration can cause them to loosen. This can be especially problematic in areas with significant temperature and humidity fluctuations, where the wood expands and contracts, putting stress on the fasteners. The outcome of these movements can lead to the eventual failure of the pickets.
The **susceptibility to pull-out** is a significant disadvantage. Nails, unlike screws, lack the threaded grip that resists extraction. Under high winds, or when the wood warps or twists, nails are far more likely to pull out of the wood, leading to pickets detaching from the rails. This is not only unsightly but also compromises the security and structural integrity of the fence.
The **limited reversibility** of nailing is another consideration. When a picket needs to be removed for repair or replacement, removing nails can be a challenge. It often involves using pry bars and risking damage to the surrounding wood. This can complicate maintenance and repairs, making the process more time-consuming and potentially more costly.
Finally, the **shear resistance** of nails is generally lower compared to screws. Shear strength refers to the fastener’s ability to resist forces that try to cut through it. This is crucial in resisting lateral forces, such as strong winds. Nails, with their smooth surface and smaller contact area, are more susceptible to shearing forces than screws.
Best Practices for Nailing
If you choose to use nails for your fence pickets, following best practices can help mitigate some of the associated drawbacks.
First and foremost, selecting the right type and size of nail is paramount. Use **galvanized or stainless steel nails** to resist corrosion, especially when working with pressure-treated wood or exposed to the elements. The length of the nail should be sufficient to penetrate the rail and the picket by a good margin, ideally at least twice the thickness of the picket material.
Correct **nail placement** is also critical. Avoid nailing too close to the edge of the picket or rail, as this can cause the wood to split. Pre-drilling pilot holes, particularly when using hardwoods, is highly recommended. This will guide the nail and prevent splitting, making the attachment process easier.
When nailing, choose the correct tools. Using a hammer is the classic approach, offering precision and control. However, a pneumatic nail gun, powered by compressed air, offers speed and efficiency, making the installation much faster, especially on larger projects.
Screwing Fence Pickets: A Modern Approach
Benefits of Using Screws
Screwing fence pickets represents a more modern approach, often favored for its increased durability and longevity. Although requiring a slightly larger initial investment, screws often prove to be a better long-term investment.
The primary benefit of screws is their **superior holding power**. Screws’ threaded design creates a strong mechanical grip that resists loosening, pulling out, and movement over time. This makes them far more reliable than nails, particularly in environments exposed to wind, rain, and temperature fluctuations.
The **durability** of screws is closely related to their enhanced holding power. The screws’ resistance to movement ensures that the pickets stay firmly attached to the rails, even under stress. This translates to a longer lifespan for the fence and reduced maintenance requirements.
The **ease of removal and adjustment** is another significant advantage of screws. If a picket gets damaged or needs to be replaced, the screws can be easily removed with a screwdriver or power drill, and the picket can be replaced without damaging the surrounding wood. This simplifies repairs and maintenance, saving time and money in the long run.
The **shear resistance** of screws is also higher than that of nails. Their design enables them to withstand significantly higher lateral forces, making the fence more resistant to strong winds and other forces that could damage the pickets.
Drawbacks of Using Screws
Despite the many advantages, screws are not without their drawbacks.
The **higher cost** of screws is a significant factor. Screws are generally more expensive than nails, which can increase the initial cost of the fencing project. This is especially noticeable for extensive fence installations, where the cost of screws can quickly add up.
The **slower installation process** is another potential disadvantage. Screwing typically takes more time than nailing, particularly if you don’t have access to specialized tools. Each screw must be driven individually, which can increase the overall installation time. However, this is often balanced out by the reduced need for repairs and replacements over the life of the fence. Using a power drill or impact driver can expedite this process.
The **visibility of screw heads** can impact aesthetics. While screws can often be camouflaged with matching paint or wood filler, the visible screw heads can detract from the clean appearance of some fences. Consider the aesthetic impact when making your decision. However, using coated screws or countersinking them can help mitigate this concern.
Best Practices for Screwing
Choosing the right screws and following best practices are essential for maximizing their effectiveness.
Selecting the correct **screw type and size** is critical. Use exterior-grade screws, designed for outdoor use and resistant to corrosion, especially for pressure-treated wood. Consider using coated screws or stainless steel screws for optimal performance. The length of the screws should be sufficient to penetrate the rail and the picket by an adequate amount, typically around 1.5 inches or more, depending on the thickness of the materials.
**Pre-drilling** is even more crucial with screws than with nails, particularly when using hardwoods. Pre-drilling a pilot hole will guide the screw, prevent the wood from splitting, and make the screwing process easier. It will also help the screw to pull the picket tightly to the rail.
**Screw placement** is also important. Screw placement affects both the appearance and the structural integrity of the fence. Locate screws in the center of the picket, and ensure they’re driven straight to achieve optimal holding power.
The selection of tools matters. A standard drill can be used for screwing, but an **impact driver** is the best choice. Impact drivers provide a much greater torque than a regular drill and are less likely to strip the screw head, and can install screws more quickly.

Making the Right Decision for Your Fence
The decision to nail or screw fence pickets depends on several factors. Carefully consider your budget, desired lifespan of the fence, the typical weather conditions in your area, and your personal aesthetic preferences before making a final decision.
If budget is your primary concern, and you are comfortable with the potential for more frequent maintenance, nailing might be a viable option, especially for temporary fencing projects or fences in sheltered locations. However, understand the trade-offs.
Screwing is generally the superior choice for most fence projects, offering greater durability, reduced maintenance, and improved long-term performance. It is highly recommended if you are building a fence in an area with strong winds, significant weather variations, or if you are prioritizing longevity.
It is important to also remember that a hybrid approach, using nails for certain components and screws for others, is possible. For instance, you could use screws for attaching the pickets to the rails and nails for attaching decorative elements.
Choosing the right fastener for your fence pickets is a crucial step in building a strong, attractive, and long-lasting fence. Assess your needs carefully, consider the trade-offs, and choose the method that best suits your project.
