In a single family dwelling, what type of screws are to be used when attaching gypsum wallboard to wood?

1. Type A

2. Type C

3. Type W

4. Type AW

The correct answer is: Type W

When attaching gypsum wallboard to wood in a single-family dwelling, Type W screws are specifically designed for this purpose. Type W screws have a coarse thread that allows for better grip in wood substrates, ensuring a secure attachment. This characteristic is particularly important in construction, as it helps to prevent the screws from stripping out during installation or over time due to settling or movement of the structure. The design of Type W screws, including their sharp point and ability to penetrate wood easily, contributes to their effectiveness in this application. They are suitable for attaching gypsum board to framing members, making them the preferred choice in most residential construction scenarios. In comparison, other types of screws like Type A or Type C are designed for different materials or uses. Type AW screws are also not as commonly specified for wood applications when attaching gypsum board. Thus, based on their design and intended use, Type W screws are the appropriate choice for this task.
