What is the correct number and size of nails needed to assemble a 2x10 timber used as a rim board and joist?

• A. 2 - 8 penny
• B. 4 - 16 penny
• C. 6 - 10 penny
• D. 3 - 12 penny

Answer: (B)

The choice of 4 - 16 penny nails is appropriate for assembling a 2x10 timber used as a rim board and joist due to several factors related to structural integrity and the load requirements of framing applications. 16 penny nails, measuring approximately 3.5 inches in length, provide sufficient holding power for the thicker lumber, like a 2x10, which is more substantial and bears significant loads. Using four nails in this setup ensures that the connection is strong enough to handle various forces, including those introduced during construction or from structural stress during use. The larger quantity of nails also distributes the load more evenly across the joint, reducing the chances of failure under heavy loads, enhancing the overall stability and strength of the assembled structure. This consideration is especially important in applications like rim boards and joists, where maintaining proper alignment and structural integrity is crucial. In contrast, other options present different sizes and quantities that may not meet the necessary holding strength for this type of work. While smaller nails may be suitable for lighter applications, in this case, the strength and number of nails specifically ensure that the timber will remain securely connected under the expected load conditions.
