When it comes to choosing the right nails for exterior trim, there are several factors to consider, including the type of nail, the material, and the finish. Finish nails, also known as finishing nails, are commonly used for exterior trim as they have a small diameter shaft that reduces the chance of splitting the wood. Brads nails, a smaller version of finish nails, are also an option but may not have the same holding strength. For those looking for inconspicuous nails, pin nails are an excellent choice as they have a very small diameter and no head. However, they may not be suitable for exterior trim due to their low holding power. Another option is stainless steel nails, which offer long-term protection against corrosion and are suitable for humid climates. Aluminum nails are also an option, especially for installing aluminum siding, fascia, and trim, as they are resistant to rust and non-toxic to trees.

What You'll Learn
Stainless steel nails are best for cedar and redwood
When it comes to exterior trim, it's important to choose the right type of nails for the job. While there are various options available, stainless steel nails stand out as the best choice for cedar and redwood. Here's why:
Cedar and redwood are unique types of wood that contain natural preservative oils and tannins. When paired with the wrong type of nail, these woods can react adversely, resulting in unsightly stains and streaks. For example, plain finish nails will oxidize and disintegrate when exposed to the natural oils in cedar. Copper nails should also be avoided as they react negatively with cedar.
Stainless steel nails, on the other hand, are non-corrosive and highly resistant to corrosion. This makes them ideal for exterior applications where they will be exposed to moisture and the elements. By choosing stainless steel, you eliminate the risk of rust and disintegration, ensuring the long-term integrity of your trim.
Additionally, stainless steel nails are specifically recommended for cedar and redwood because they do not react with the natural oils and tannins present in these woods. This compatibility ensures that your trim remains stain-free and aesthetically pleasing. For Western Red Cedar, in particular, hot-dipped galvanized, aluminum, and stainless steel nails are recommended as they are all corrosion-resistant.
When working with cedar, it's important to consider the length of the nail as well. As a general guideline, select a nail length that is approximately twice the thickness of your cedar. This ensures a secure hold without the point of the nail poking through the other side. For greater holding power, opt for nails with ring threaded or spiral threaded shanks.
In summary, stainless steel nails are the best choice for cedar and redwood exterior trim due to their corrosion resistance, compatibility with the wood's natural oils, and the availability of various lengths and shank types. By choosing stainless steel, you can be confident in the durability and aesthetics of your trim for years to come.

Finishing nails are used in fine carpentry and cabinetry
Finishing nails are also known as casing nails, which are simply larger versions of finishing nails. Casing nails are often used for installing exterior trim boards, nailing door frames, and trim. They have flat heads, which help prevent the wood from splitting when the nail is driven in. Casing nails are commonly made of galvanised steel for corrosion resistance.
Finishing nails are also similar to brad nails, which are smaller and thinner and used for light woodworking, cabinetry, and craft work. Brad nails are also used for attaching trim and moulding, as well as light-duty upholstery projects. They are less likely to split wood due to their small size.
Another type of nail used for exterior trim is box nails, which are similar to common nails but have thinner shanks. They are better suited for thinner wood materials, such as exterior trim. However, they should not be used for structural projects as they lack the strength and holding power of common nails.
When choosing nails for exterior trim, it is important to consider the type of wood and the level of holding power required. For example, stainless steel fasteners are recommended for cedar and redwood to prevent rusting, while galvanised nails should be avoided as they will react with the tannins in the wood.

Hot-dipped galvanised nails are suitable for exterior use
The galvanisation process helps to protect the nails from corrosion and rust, ensuring their longevity in outdoor conditions. This is particularly important when using pressure-treated lumber, which is commonly used in exterior construction. The zinc coating acts as a barrier between the nail and the elements, preventing moisture and chemicals from causing corrosion.
Hot-dipped galvanised nails are often used in outdoor construction projects, such as securing exterior trim, gutters, and fascia boards. They are also suitable for use with treated lumber, which is typically used in outdoor structures to prevent wood rot and insect damage. The combination of hot-dipped galvanised nails and treated lumber helps to ensure the durability and longevity of the project.
While hot-dipped galvanised nails are suitable for exterior use, it is important to consider the type of wood being used. For example, when working with cedar or redwood, stainless steel fasteners are recommended to avoid reactions with the tannins in the wood, which can occur even if the wood is painted. In such cases, hot-dipped galvanised nails may not be the best choice and could lead to rust and corrosion.
Overall, hot-dipped galvanised nails are a reliable option for exterior trim and other outdoor applications, providing superior protection and durability compared to some other types of nails. The hot-dipped galvanisation process ensures a thick zinc coating, making the nails more resistant to environmental factors that can cause corrosion and rust. However, it is always important to consider the specific materials being used in a project to ensure compatibility and avoid potential issues.

Pin nails are used with nailers and have a very small diameter
When it comes to exterior trim, selecting the right type of nail is crucial. Trim nails are specifically designed for exterior use on homes. Finish nails, also known as finishing nails, are commonly used in fine carpentry and cabinetry, and they are suitable for moulding. These nails have a small diameter shaft, typically ranging from 16 to 10 gauge, reducing the likelihood of splitting the workpiece.
For exterior trim, it is essential to consider nails that can withstand outdoor conditions. Hot-dipped galvanised nails, for instance, are suitable for exterior use and are compatible with treated lumber. However, it is important to note that galvanised nails may not be suitable for certain types of wood, such as cedar, as they can react with the tannins and cause rusting. In such cases, stainless steel fasteners are recommended.
Now, let's focus on pin nails. Pin nails are specifically designed for use with nailers, also known as nail guns. They have a very small diameter, typically 23 gauge, and are headless. Due to their small size, they do not provide significant holding power, but they excel in inconspicuousness. Pin nails are ideal for delicate trim work and softer woods, ensuring precision and minimising the risk of splitting the wood. When using pin nails, it is common to combine them with glue to secure thin veneer and small pieces of moulding and trim effectively.
The choice between pin nails, brad nails, and finish nails depends on the specific requirements of your project and the type of wood being used. Brad nails are a versatile middle ground between pin and finish nails. They are typically made from 18-gauge steel wire, providing more holding power than pin nails, and are suitable for various applications such as crown moulding work, cabinetry, and furniture building. Finish nails, on the other hand, are thicker and offer a stronger hold, making them ideal for denser woods and heavy-duty finishing projects.
In summary, when considering nails for exterior trim, it is important to select nails suitable for outdoor use, such as hot-dipped galvanised nails or stainless steel fasteners. Pin nails, with their very small diameter, are ideal for use with nailers and are perfect for delicate trim work and temporary holding while glue dries. Brad nails offer more holding power and versatility, while finish nails provide the strongest hold for denser woods and heavy-duty projects.
