Question

what should be used when nailing a rim joist to the sill plate? 8d nails at 6\ oc 8d nails at 8\ oc 16d nails at 12\ oc 16d nails at 18\ oc

Explanation:

When nailing a rim joist to the sill plate, 16d nails at 12" OC (on - center) are typically used. 16d nails provide sufficient holding power for this structural connection. Nailing at 12" OC ensures a proper and secure attachment. 8d nails are generally too small for this heavy - duty connection (rim joist to sill plate which is a critical part of the floor system's structural integrity). And nailing at 18" OC would be too spaced out to provide adequate strength.

Answer:

16d nails at 12" OC
