How long is an 8d common nail?

1 inch
2 inches
2 1/2 inches
3 inches

The correct answer is: 2 1/2 inches

An 8d common nail, commonly used in carpentry and construction, measures 2 1/2 inches in length. The "8d" designation comes from the penny system, where the "d" stands for "penny," a term that has its roots in historical trade practices. Traditionally, a nail's size in the penny system corresponds to its length: an 8d nail is specifically standardized to 2 1/2 inches. Understanding the sizes of nails and their corresponding lengths is crucial for home inspectors, as it allows them to assess the suitability of materials used in construction and renovation work. Knowledge of hardware specifications like this is essential for accurate inspections and recommendations.
