Which type of nail is typically smaller and used for light construction and finishing work?

Brads and finishing nails are specifically designed for light construction and finishing work because of their smaller size and finer gauge, which allows them to be used in applications where precision and a less obtrusive appearance are important. These types of nails are ideal for attaching thin pieces of trim, molding, or other delicate materials without splitting them or leaving large holes that are difficult to hide.

Brads, often used with a pneumatic nail gun, are particularly effective for lightweight materials and can be driven in smoothly, leaving a minimal point of entry. Finishing nails serve a similar purpose, providing enough strength to hold items together while being easily concealed with wood putty or varnish once installed.

Other nail types mentioned, like common nails, double-headed nails, and spikes, serve different purposes; they are typically larger and designed for heavier construction work or structural applications, where strength is more critical than aesthetics. Thus, brads and finishing nails are the preferred choice for lighter tasks where a clean finish is essential.
