In the world of finish carpentry and woodworking, the choice of fasteners is crucial. Two common options for finish nails are FN and DA style nails. In this article, we will explore the key differences between these two types of finish nails, providing precise and clear information that’s accessible to both technical experts and beginners.
FN Style Finish Nails
FN style finish nails, short for "F-brad Nails," are also known as 16-gauge finish nails. They are a popular choice for a variety of finish carpentry applications. Here are the key characteristics of FN style finish nails:
-
Gauge: FN nails are 16-gauge nails. The gauge refers to the thickness of the nail. In this case, a lower gauge number indicates a thicker nail.
-
Head Type: FN nails often feature a small, flat head. This head type is designed to offer a low-profile finish when driven into the wood. It minimizes the need for wood putty or filler.
-
Applications: FN style nails are suitable for a wide range of applications, including trim work, baseboards, crown molding, and attaching small wood pieces.
-
Nail Length: These nails come in various lengths, typically ranging from 1 inch to 2.5 inches. The choice of nail length depends on the thickness of the wood and the specific project requirements.
DA Style Finish Nails
DA style finish nails, standing for "D-head Nails," are typically 15-gauge nails. They have their own distinct features and applications:
-
Gauge: DA nails are 15-gauge nails, which are slightly thicker than FN nails, making them stronger and more suitable for heavy-duty applications.
-
Head Type: DA nails feature a "D" or "depressed" head, which provides a larger surface area for holding power. This design is intended for increased stability and holding capacity.
-
Applications: DA style nails are often used for attaching heavy moldings, large trim, and other applications where additional strength and support are required.
-
Nail Length: Like FN nails, DA nails are available in various lengths, typically ranging from 1.25 inches to 2.5 inches.
Key Differences
The main differences between FN and DA style finish nails are as follows:
-
Gauge: FN nails are 16-gauge, while DA nails are 15-gauge. The lower gauge number of DA nails indicates a thicker and more robust nail.
-
Head Type: FN nails have a small, flat head, while DA nails feature a larger, "D" shaped head for enhanced holding power.
-
Applications: FN nails are suitable for a broad range of finish carpentry tasks, while DA nails are typically reserved for heavy-duty applications that require more strength and stability.
Conclusion
In summary, the choice between FN and DA style finish nails should be based on the specific requirements of your project. FN nails are excellent for general finish carpentry work, providing a clean and inconspicuous finish. On the other hand, DA nails are preferred for applications where added strength and holding power are essential. By understanding the differences between these two nail types, you can make an informed decision and achieve the best results in your finish carpentry projects.
