What type of nail is suitable for nailing boards where the head will not be noticed?

A finishing nail is specifically designed for applications where the head will not be visible after installation. This type of nail is typically slender and has a small, often slightly rounded head, which allows it to be driven below the surface of the wood with the use of a nail set. This characteristic minimizes the visibility of the nail, making it ideal for tasks such as assembling trim and molding, or when working on fine woodworking where aesthetics are important.

In contrast, flathead stove bolts and flathead wood screws are more prominent in their designs, as they are intended to remain visible in applications where strength and secure fastening are priorities rather than cosmetic appearance. A flaring tool, on the other hand, is not a fastening device and serves an entirely different purpose in metalworking. Therefore, for projects where you want the nail to blend seamlessly with the surrounding material, a finishing nail is the optimal choice.
