What type of fastener may be used for vinyl siding with a minimum thickness of 0.035 inch when installed to foam plastic sheathing?

The proper choice is a nail with a diameter of 0.120 inches and a head size of 0.313 inches because it meets specific requirements for securing vinyl siding, particularly when installed over foam plastic sheathing. This type of fastener provides adequate holding strength and structural support to ensure that the vinyl siding remains in place against various weather conditions and external forces.

Using nails with the specified dimensions ensures that they penetrate deep enough into the structure while distributing pressure effectively across the foam sheathing, minimizing the risk of damage. Additionally, the larger head size helps to prevent the fastener from pulling through the siding, which is critical in maintaining the integrity and aesthetics of the installation.

Other fastener types listed either do not meet the necessary specifications for thickness and head size needed for optimal performance with vinyl siding or would not provide the same level of support needed for this application. For example, staples may not offer the same holding strength as nails and could result in sagging or detachment over time. Galvanized screws, while durable, may not typically be used in the same context as nails for this specific application. Hence, the selected fastener option is the most effective choice for installing vinyl siding on foam plastic sheathing.
