What are commonly used nails typically referred to as?

Commonly used nails are referred to as common nails. These nails are designed for general-purpose use in construction and carpentry, favored for their strength and ability to hold materials together securely. They typically have a thick shank, which gives them the strength required for structural applications, and a flat head that allows for easy driving and a flush finish.

The term "common nails" encompasses a variety of sizes, but they are primarily used for framing, sheathing, and other high-stress applications. Their wide availability and reliability make them a staple in both professional and DIY projects.

In contrast, other types of nails such as brads and finishing nails are designed for more specific applications, often where a less visible nail head is desired. Spikes, on the other hand, are larger and used for heavy construction applications, such as in bridging or rail construction. Double-headed nails are typically used in situations where the nail needs to be removed later, often in temporary structures.
