When fastening edges of 5/8 inch thick plywood to floor joists with 8d nails, what is the maximum allowable spacing on center?

The maximum allowable spacing for fastening edges of 5/8 inch thick plywood to floor joists using 8d nails is determined based on the structural requirements to ensure proper support and stability of the flooring system. In this case, 6 inches on center is deemed appropriate because it provides a balance between adequate fastening strength and material efficiency.

When wood floor sheathing is installed, maintaining the right spacing helps to distribute loads evenly and minimizes the potential for movement that could lead to squeaking or structural issues over time. This spacing is also aligned with common building codes and best practices in the construction industry, which often dictate specific fastening requirements based on material thickness and type of fastener used.

Understanding these standards not only helps in completing a safe and durable installation but also ensures compliance with local building regulations, thus emphasizing the importance of adhering to guidelines when working on flooring projects.
