Brad nails are thin, 18-gauge nails that are smaller in diameter than finish nails and typically have less holding strength. They are commonly used for lightweight, indoor applications, such as attaching shoe moldings, small ornamental parts on furniture, and light decorative trim and molding. Brad nails are also useful when gluing delicate wooden parts together, as they have a smaller head size that makes them easier to conceal in small pieces of wood trim. Because of their small diameter, brads may be more difficult to hold in place and are prone to bending. Brad nails are ideal for many woodworking projects because they leave a less visible hole, making them perfect for fine carpentry and craft jobs or any application that doesn’t require powerful holding strength. Brad nails are usually not galvanized, so they’re not good for exterior applications as they’re prone to rusting. Brad nails are often used with a brad nailer, which is a light-duty tool that is easy to load and use.
