A standard Number 5 reinforcing bar has a diameter of what?

The diameter of a standard Number 5 reinforcing bar is 5/8 inch. This size is commonly used in construction for reinforcing concrete, providing enhanced structural integrity and load-bearing capacity. Understanding the sizing system for rebar is crucial for carpenters and those working in construction, as it ensures proper selection of materials to meet engineering specifications. The number associated with the rebar size corresponds to the number of eighths of an inch in diameter; therefore, a Number 5 bar being 5/8 inch supports this convention accurately. Knowing this measurement helps ensure that the bars will fit correctly into the structural elements being reinforced.
