Even though a hammer and nail may seem like the most basic tools, do you know which nail to use for each job? Just like hammers, nails have the right and wrong uses. When choosing a nail, consider its strength, size, and other design elements. Using the improper type of nail can weaken the joint and even destroy the wood.
To ensure the best possible hold in various applications, nails come in a wide variety of diameters and shaft styles. In this article, we’ll answer the questions what are finish nails used for and what are the most popular finishing nail uses?
What is a Finish Nail?
Okay, so let's get the basics out of the way. Simple physics explains how nails function. When a nail is driven into wood, its shank forces wood fibers apart as the point pierces the surface. Nails have their holding power because of the friction that results from the displaced wood fibers grasping the nail shank.
Finish nails are ideal for thicker wood. They come in bulk, hand drive, and are collated in strips designed for use with nail guns. The length of the nails can vary from 3/8 inch to 2 1/2 inches. Their thicker gauge gives projects more holding power. Their thicker gauge gives projects more holding power, making them perfect for both professional contractors and DIY enthusiasts.
One of the most common finishing nail uses is attaching trim and molding where appearance matters. Because the heads are small and sink below the surface, they’re easier to conceal with filler and paint for a seamless finish.
What Are the Sizes of Finish Nails?
Small finishing nails have incredibly tiny heads. Typically, they are utilized for "finishing touches" like molding or trim. For a smooth finish and an indiscernible nail and nail hole, they often sink into the surface, leaving a hole that needs to be filled with putty and painted over.
Steel finishing nails are available in a variety of gauges. The gauge sizes range from 15 to 18 gauges, with lower gauge sizes resulting in stronger nails. For example, many carpenters often ask what 16-gauge nails are used for. These are a versatile choice for medium to large trim projects because they strike a balance between holding strength and a clean, professional look.
The length of finishing nails can range from 3/8 inch to 2 1/2 inches, allowing them to adapt to many different woodworking applications.
What Are Finish Nails Used For?
Finish nails are constructed of heavier15- or 16-gauge wire, which allows them to support a heavier payload. A finish nail is preferable for bigger trim, such as baseboards or crown molding. A finish nail is a superior option when installing larger trim and woodwork due to its improved support and withdrawal resistance.
Heavier gauges are particularly important in tough jobs. For instance, when people wonder what 15-gauge nails are used for, the answer is usually projects requiring maximum holding strength, like door frames, hardwood flooring, and structural trim, where durability is critical.
Finishing nails are your best bet for high-wear areas like doorway trim, as they are much more difficult to remove. Using a finish nail of the proper length, paneling can be hung over drywall and fastened to the studs.
In most cases, finish nails will leave a tiny indentation on the surface; thus special care must be taken when applying them. To disguise a nail head, countersink with a nail punch. Despite the extra step, finish nails are still favored for bigger trim and carpentry projects.
Choosing the Right Gauge for Your Project
Since finishing nails are available in multiple gauges, the right size depends on the balance you need between holding power and appearance. If you’re wondering what 18-gauge nails are used for, they’re best for lighter trim, smaller moldings, or decorative wood pieces where you don’t want to risk splitting delicate material.
On the opposite end of the spectrum, ultra-thin options exist as well. For example, what 23-gauge nails are used for comes down to fine detail work—like attaching thin trim, small decorative pieces, or cabinetry where you need an almost invisible fastener. While they don’t have as much holding power, they leave the cleanest finish of all.
