To secure studs to either the top or bottom plates, how many nails are typically used?

When securing studs to either the top or bottom plates in framing, using two 16D nails is common practice. The 16D nails, which are 3.5 inches in length, provide enough holding power to securely fasten the studs, especially in load-bearing walls. This length allows them to penetrate deeply into both the studs and the plates, creating a strong connection that helps ensure the structural integrity of the wall.

Using two nails is standard in framing to distribute the load and create a secure attachment while also allowing for slight movement without risking damage. The choice of using 16D nails instead of other sizes, like 8D or 10D, is primarily due to the need for greater strength in framing applications, particularly in areas subject to tension and shear forces. The use of larger nails also helps counteract the potential for splitting the wood.
