A contractor is installing wood board siding to the exterior of a house. The fasteners must penetrate the studs a minimum of?

The requirement for fastener penetration into the studs during the installation of wood board siding is critical to ensure strong and durable attachment. A minimum penetration of 1 inch is specified to provide adequate holding strength and stability. This depth ensures that fasteners are securely embedded within the structural framing, contributing to the overall integrity of the siding installation.

Penetration that is too shallow could result in the fasteners being unable to adequately support the weight or withstand environmental conditions, leading to potential failure of the siding over time. Additionally, a 1-inch penetration strikes a balance between sufficient strength and the risk of compromising the structural integrity of the stud itself or creating issues such as splitting.

In contrast, options suggesting greater or lesser penetration may not meet the code requirements or best practices for installation, which emphasize the importance of proper fastener depth for durability and adherence to building standards.
