What Size Nails For Hardwood Flooring?

Installing hardwood flooring is a great way to add beauty and value to your home, however, choosing the right size nails is essential to ensure a secure and long-lasting installation. Using nails that are too small can lead to the flooring buckling or coming loose, while nails that are too large can split the wood or damage the subfloor.

The size of nails for hardwood flooring is determined by the thickness of the flooring and the type of subfloor. For 3/4-inch thick hardwood flooring, 15-gauge nails are typically used. For 5/16-inch thick hardwood flooring, 16-gauge nails are typically used. For 1/2-inch thick hardwood flooring, 18-gauge nails are typically used.

When choosing nails for hardwood flooring, it is also important to consider the type of subfloor. For plywood subfloors, ring-shank nails are recommended. Ring-shank nails have a series of rings around the shank that help to prevent the nails from pulling out of the subfloor. For concrete subfloors, screw nails are recommended. Screw nails have a threaded shank that helps to anchor the nails into the concrete.

In addition to the size and type of nails, it is also important to use the correct nail length. The length of the nail should be about 2-1/2 inches long, so that it can penetrate through the hardwood flooring and into the subfloor by about 1-1/2 inches.

By following these tips, you can choose the right size nails for your hardwood flooring installation and ensure a secure and long-lasting installation.
