Coastal and Floodplain Construction Inspector's Practice Exam

What fastener type is required to attach sheathing to roof framing?

1. 8d common or 8d hot dipped galvanized

2. 8d steel or 10d galvanized

3. 6d common or 6d galvanized

4. 6d steel or 8d common

The correct answer is: 8d common or 8d hot dipped galvanized

To fasten sheathing to roof framing effectively, the appropriate fastener type typically used is the 8d common or 8d hot dipped galvanized nail. The designation "8d" refers to a specific size of nail, which provides the necessary length and holding power for securing sheets of sheathing material, such as plywood or oriented strand board (OSB), to the roof structure. The use of hot-dipped galvanized nails is important when considering moisture resistance, especially in coastal and floodplain construction where exposure to elevated humidity or direct water contact can lead to corrosion. This galvanization process creates a protective layer around the nails, making them suitable for use in areas where the nails may be subject to adverse weather conditions. Selecting the right fastener is crucial as it ensures the sheathing is securely adhered, providing structural integrity and helping to protect the building from the elements. In choosing the proper fastening system, factors such as nail length, corrosion resistance, and suitability for the specific materials being used are key considerations; hence, the 8d common or hot dipped galvanized nails meet these criteria effectively for attaching roof sheathing.
