What Nails To Use For Plywood Subfloor?

When installing a plywood subfloor, choosing the right nails is crucial for a stable and squeak-free foundation. For most subfloor applications, we recommend using ring shank nails. These nails have circular ridges along the shank that provide superior holding power and resist loosening over time.

The ideal nail size for plywood subfloors is typically 2 inches (50.8 mm) in length. These sizes ensure strong fastening and minimize the risk of subfloor movement, keeping the foundation stable.

We suggest using 8d ring shank nails, which have a diameter of 0.0915 inches (2.32 mm). These nails offer excellent holding strength and are suitable for most residential subfloor installations.

For thicker plywood or in high-traffic areas, you might consider using 10d ring shank nails, which are 3 inches (76.2 mm) long with a diameter of 0.1205 inches (3.06 mm). If using longer nails, always check for hidden utilities to avoid accidental damage.

When installing your subfloor, it’s important to follow proper nailing patterns and spacing. Typically, nails should be spaced 6 inches (152.4 mm) apart along the edges of the plywood sheets and 12 inches (304.8 mm) apart in the field.

Following these nailing patterns not only secures the subfloor but also helps prevent squeaks over time.
