When installing a new 3/4 inch plank hardwood floor over a sub-floor, the plank flooring shall be nailed every _ inches?

When installing a new 3/4 inch plank hardwood floor over a sub-floor, the best practice is to nail the plank flooring every 8 inches. This spacing ensures that the flooring is adequately secured to the sub-floor, providing stability and reducing the likelihood of movement, squeaking, or other issues that can arise from insufficient fastening. Nailing every 8 inches strikes a good balance between holding the planks securely while allowing for some natural expansion and contraction of the wood due to changes in temperature and humidity. This method enhances the longevity of the installation and improves the overall performance of the flooring.

In contrast, faster or wider nailing intervals might not provide the necessary support, potentially leading to problems down the line.
