What is the minimum spacing for nails and screws in a braced wall line using 1/2 inch gypsum board?

7 inches
8 inches
12 inches
16 inches

The correct answer is: 12 inches

The minimum spacing for nails and screws in a braced wall line using 1/2 inch gypsum board is 12 inches. This guideline is based on building codes and standards that ensure proper attachment and performance of the gypsum board in resisting lateral loads. Spacing nails and screws at this distance helps to effectively distribute the load across the braced wall, which is crucial for maintaining structural integrity during events such as high winds or earthquakes. Additionally, it minimizes the risk of board movement or failure over time, ensuring that the wall continues to perform as intended in terms of both strength and fire resistance. When considering other spacing options, such as 7 inches, 8 inches, and 16 inches, these do not meet the established standards for spacing in braced wall lines, either being too close or too far apart, which could compromise the wall's overall stability and effectiveness in load-bearing situations. Keeping to the prescribed 12-inch spacing helps to adhere to safety and performance standards in construction practices.
