Nails for Pressure Treated Wood A Guide to Choosing the Right Fasteners

When it comes to building with pressure treated wood, one crucial aspect that can often be overlooked is the selection of the right nails and fasteners. Pressure treated wood is commonly used in outdoor structures such as decks, fences, and pergolas due to its enhanced resistance to decay and insects. However, the chemicals used in the treatment process can adversely affect certain types of fasteners if they are not properly chosen. In this article, we will explore the best nails for pressure treated wood and why selecting the right ones is essential for the longevity and durability of your outdoor projects.

Understanding Pressure Treated Wood

Pressure treated wood undergoes a chemical process to enhance its durability, making it less susceptible to rot, termites, and other environmental damages. This wood is typically used in applications where it will be exposed to moisture, such as in deck boards, posts, and landscaping projects. However, the pressure treatment often involves the use of copper-based preservatives, which can corrode certain metals and fasteners over time.

Types of Nails Suitable for Pressure Treated Wood

1. Stainless Steel Nails Stainless steel is perhaps the best option for fastening pressure treated wood. It is highly resistant to corrosion, thus ensuring a long-lasting bond even in harsher outdoor environments. While a bit more expensive than other types of fasteners, stainless steel nails provide the peace of mind that your structure will maintain its integrity.

2. Galvanized Nails Another option is hot-dipped galvanized nails. These nails are coated with a layer of zinc, which provides a barrier against moisture and corrosion. However, it’s important to note that not all galvanized nails are created equal. Make sure to choose nails that are rated for use with pressure treated wood to ensure durability and performance.

3. Epoxy-Coated Nails Epoxy-coated nails can also be used in conjunction with pressure treated wood. The epoxy coating provides a level of protection against corrosion, making these nails durable for outdoor use. They are typically less expensive than stainless steel but may not last as long in very wet or treated environments.

4. Aluminum Nails While aluminum is resistant to rust, it is not recommended for use with pressure treated wood because it can react chemically with the wood's preservatives, potentially leading to corrosion and failure over time. It’s best to avoid aluminum nails for any structural applications involving pressure treated wood.

Factors to Consider When Choosing Nails

- Corrosion Resistance Given the nature of pressure treated wood, always prioritize nails that are resistant to corrosion. The right choice will prevent structural failure and extending the life of your project.

- Strength and Holding Power Ensure that the nails you choose are strong enough to hold the weight of the materials being fastened. For pressure treated wood, opt for nails that are specifically designed to handle the stresses of outdoor applications.

- Length and Size The length and size of the nails are also critical for the effectiveness of the fastening. Generally, nails should penetrate at least one and a half times the thickness of the material being fastened to ensure a strong bond.

Conclusion

Choosing the right nails for pressure treated wood is essential for ensuring the integrity and durability of your outdoor projects. Stainless steel, hot-dipped galvanized, and epoxy-coated nails are the top choices that will help protect your work against corrosion and deterioration. By prioritizing quality fasteners and understanding the implications of using the wrong type, you can ensure that your constructions stand the test of time, providing you with beautiful and reliable outdoor spaces for years to come.
